MacOS platform build cleanup.
DETAILS:
Since the libctx changes, stdio hasn't been directly available.
Therefore we no longer support '-' as a special filename in
(the obsolete) gp_open_printer(). We change an fprintf(stderr,...)
to an eprintf() which is more correct in any case.
This change also removes the fprintf() and fputs() implementations
in the MacOS build. Metrowerks CW libc has for some time provided
implementations, but they're even less needed now that we're being
a proper library.
Convert gs_malloc() calls in the MacOS gp_* code to unwrapped libc malloc()
now that gs_malloc() requires a memory pointer, which is not available.
Partial fix for bug 687830.
DETAILS:
Only the call in getenv() is active; the one in gp_init() is not used.
This may have been what the earlier libctx patch was trying to do when
it touched gp_macio.c, changing the function call, but not the arguments,
and breaking the

Added macros for assertions:
GS_ASSERT(false)
returns -1 in a release system
asserts in a debug system
GS_DBG_ASSERT(false)
is a NOP in a release system
asserts in a debug system
Both versions will printf to stderr first.
Raw assert() should not be used.
GS_ASSERT will not compile in a void function, as it returns -1.
This means you can not use assertions to change the standard error return
exception handline mechanism in Ghostscript.
You can use them to catch programmer usage errors in a debug build.
gs_misc::gs_assert() is the one place the operating system's assert is called.
This can be modified in a embedded system, again assert is only called in
a debug build.

Fix: in implementation of n operator in clip mode, put pathbbox in stopped
context so that completely empty paths have the same behavior as paths
with empty bbox, rather than causing an error. Fixes bug #687820.
DETAILS
The test file has a "n W n" sequence, which is a request to clip to
a totally empty path. The error comes from code added to pdf_ops.ps v
1.33 to handle the case where a path is defined but has an empty
bbox. See bug 687136 for more details on this change. Comment #8 of
that bug report suggests that our PDF interpreter always maintains a
currentpoint, which would justify the use of an unprotected
pathbbox. However, that assumption seems to be false. This fix wraps
the pathbbox added in the 1.33 change in a stopped context.

Add a platform-specific JASPERCFLAGS makefile variable to assist with
proper compilation of the jasper jpeg2k library. Set this variable
correctly in the autoconf build.
DETAILS:
The jasper library natively supports building under both autoconf+cc and
MSVC, but expects a preprocessor define to be set to distinguish the
two. While we do carefully construct a special JAS_CC for compiling the
jasper source into Ghostscript, as with all the other 3rd party
libraries, there is only a facility to set special CFLAGS globally.
This change adds a new top-level makefile variable for passing
platform-specific CFLAGS into gs.mak for addition to that global
set.
Also, set JASPERCFLAGS=-DJAS_CONFIGURE in Makefile.in so that the jasper
sourcr expects the autoconf generated configuration header when
compiling as part of Ghostscript.

Copies over new-style color procs when making a null device with a
target, to avoid inconsistent states. Fixes bug #687770.
DETAILS
The problem was a null device (for implementing stringwidth) with
inconsistent color info; the color_info struct specified 4 components,
but the get_color_mapping_procs was
gx_default_DevGray_get_color_mapping_procs, which is the desired value
for null devices instantiated through gs_copydevice
(i.e. -sDEVICE=null). As a result, cm_comps[1] through [3] were left
uninitialized, and, when negative, would crash the halftone logic.
This patch copies over the new-style color mapping procs (the
old-style were already copied) in the gs_make_null_device routine. A
strong argument could be made for changing the logic in
gx_device_copy_color_procs() instead, but it was felt that this change
was more localized.
Dan reviewed this patch during a phone conversation, so I am going ahead
and committing. I'm also opening a new bug to encourage a closer look
at other uses of gx_device_copy_color_procs() to see whether a change
there is beneficial or harmful.

Add utility mkcidfm.ps to create a cidfmap file based on fonts
found in a directory.
Change MS-Windows installer to optionally update lib/cidfmap
with the CJK fonts found in the Windows font directory.
DETAILS:
Ghostscript does not ship with CJK fonts.
If support for Chinese, Japanese or Korean is added to MS-Windows,
CJK TrueType fonts and font collections are added to the MS-Windows
fonts directory. These can be used by ghostscript by specifying
mapping and aliases in the lib/cidfmap file.
This patch looks in the MS-Windows fonts directory for known
CJK fonts, and if present it appends appropriate mappings or
aliases to the lib/cidfmap file.
The font names and aliases are currently fixed, but can
be changed by editing mkcidfm.ps.
A new checkbox is added to the installer dialog
"Use Windows TrueType fonts for Chinese, Japanese and Korean"
Only if the user selects this will lib/cidfmap will be updated.

Fix for Bug 687459 (SEGV) addressing several problems: (i) Elements
fetched from a font dictionary have to be dereferenced into a ref
since pointers change if the dictionary is resized (to add entries);
(ii) The glyph_cache used by gs_font_cid2 fonts needs to be in stable
memory since elements might be added after a 'save' and the list will
still be refereced by the font, so cannot be freed by 'restore';
(iii) The gs_glyph_cache__release was never being called so creating
a memory leak -- font notification (called by gs_font_finalize) is
now used to free the cache list; (iv) The gs_glyph_cache__release
did not work (probably was never tested since it was not being used).
DETAILS:
Using stable_memory means that the objects created need to be freed
properly, that's why the font_notify mechanism was used. This fixes
the problem reported by the bug and doesn't seem to have created
any other problems (regression test passed).
A 'memory' element was added to the gs_glyph_data_s structure so
that the 'bits' can be allocated using the desired memory (stable
memory in the case that we are using the cache). This was deemed
preferable to always using the pfont->memory->stable_memory since
changing to this might cause other problems. This did create a
fair number of changes since every place the get_outline was used,
the glyph_data structure needed to have the 'memory' element set.
We could have used 'NULL' to signal pfont->memory, but this might
have masked uninitialized memory issues that can be tracked with
tools such as valgrind.
The gs_glyph_cache__release was totally broken, and since it was
not previously used, fixing and testing it presents no risk of
other clients relying on broken behaviour.
The implementation of the cache is VERY RUDIMENTARY -- a linked
list of elements with a hard-coded number (32767) limit to the
size of the cache. The size is too small to be useful for Asian
fonts, but making it bigger will result in a lot of time spent
finding a 'miss' condition. At least the current logic has LRU
slot re-use behaviour (which should be retained). Fixing this,
and making the cache limit larger are left for a later change
(post 8.50 release).

Fix : toolbin/pdfinflt.ps did not decompress some streams (continued).
DETAILS :
The 2nd Patch from SaGS for the bug 687746
"gs\toolbin\pdfinflt.ps doesn't unpack a stream"
The previous patch contained on over-optimization that leaded to a corrupted
operand stack. "{ [ {proc} {proc} ] }" (note: 2 identical inner procs)
can be optimized:
either as "{ [ {proc} dup ] }" - use VM for only 1 copy of "{proc}"
or as "{ { {proc} {proc} } }" - the 2-element array is allocated
only once, by the parser, not at
each execution of the enclosing proc
but we cannot apply both these optimizations at the same time.
This error affects PDF files that include a /Filter and/or /DecodeParams
specified as 1-element arrays. PDFs for which these entries are a single
name (for /Filter) or dict (for /DecodeParams) or arrays with 2 or more
elements are not affected.

Fix (pdfwrite) : Forget cancelled resources.
DETAILS :
Bug 687749 "PS to PDF generates very large PDF document"
1. An indeterministic bug fixed in gdevpdfi.c, hunk #1.
2. Implemented a recognition of equal patterns in gdevpdfi.c
and provided a PDF pattern substitution.
We caould not provide a substitution in the PS interpreter
because an accumulated pattern instance doesn't point
to the corresponding client color.
3. pdf_forget_resource is applied when a resource is cancelled and
is not longer needed. This applies to all redundant resources except patterns,
because patterns keep the substitution data.
We would like to save memory from substitured patterns with
a special substitution table,
but we have no time for such optimization now.
4. The function pdf_forget_resource is some slow
because the data structure was not designed for
removing resources from lists.
We would like to implement dual linked lists,
but we have no time for such optimization now.
5. Since pdf_forget_resource is not applied to patters,
we need to prevent a big growth of the number of stored patterns.
We implemented pdf_drop_resources for that purpose
and drop all substitured pattrens after 300 ones
have been accumulated, but not frequenter than once per page.
This solution isn't perfect, but should work for most cases.
If a substituted pattern is dropped erroneusely,
it will be accumulated again, maybe causing some slowdown.
6. Implemented a new device parameter PrintStatistics.
The new function pdf_print_resource_statistics
prints a statistics to stdout.

Fix (type 1 interpreter) : Replaced Metrics was missed.
DETAILS :
Bug 687614 "mirrored glyph is rendered at incorrect position".
This patch fixes the problem for raster devices.
Without -dNOCACHE the behavior was indeterministic due to
uninitialized cxs.use_FontBBox_as_Metrics2 in zchar1.c.
We ported the change from gstype1.c to gstype2.c with no special testing
because we have no practical examples of Type 2 with a replaced lsb.
It happens so because Type 2 only appears in PDF, which doesn't replace lsb.

DETAILS :
Bug 687603 "vertical text misplaced after distilling", reopened.
Bug 687753 "Text not aligned when viewed with Acrobat Reader", re-testing.
Disposition :
D1. The PDF spec requires X-compomenent of v-vector always equals to half glyph width.
D2. AR5 appears to use W|DW to compute the X-component of the v-vector of WMode 1.
The previous patch fixed most problems, but one left unfixed.
When a glyph is used with WMode 0, and later with WMode 1,
the second usage doesn't store Width and V due to the 'used' flag is already set.
This patch introduces 2 separate sets of flags for WNode 0 and WMode 1.
Changes :
1. Defined a new field 'used2' fro WMode 1 in gdevpdtf.h .
2. Allocated the used2 array, provided garbager methods,
and a resizing on demand in gdevpdtf.c .
3. gdevpdtc.c sets used2.
4. Improved the computation of the v-vector in gdevpdtt.c .
Now pdf_glyph_widths should be conforming to (D1) and (D2).
5. The coordinate adjustment in gdevpdte.c is not longer useful
due to (4). Removed.
6. When writing W, W2, glyphs are being enumerated with used, used2
correspondingly (gdevpdtw.c).
7. The accedd to Widths2 sometimes was incorrect. Now fixed (gdevpdtf.c).
8. gdevpdtc.c misused Widths2 as Widths when storing the WMode 0 width
as a component of theWMode 1 v-vector. Now fixed.

Fix (pdfwrite, PDF interpreter) : Glyph positions were wrong for vertical CID fonts.
DETAILS :
Bug 687753 "Text not aligned when viewed with Acrobat Reader".
Disposition :
D1. The PDF spec requires X-compomenent of v-vector always equals to half glyph width.
D2. AR5 appears to use W|DW to compute the X-component of the v-vector of WMode 1.
Changes :
1. With WMode 1, pdf_obtain_cidfont_widths_arrays obtains both Widths and Widths2 arrays
(gdevpdtf.c, gdevpdtf.h, gdevpdtc.c).
2. For CID fonts gdevpdtc.c computes both WMode 1 and WMode 2 width
when WMode 1 is requested.
3. Due to (D1), must compensate the half width when computing a glyph position
in gdevpdte.c (hunk #2).
4. In gdevpdte.c internal data glyph_origin_shift used opposite signs for
CID and non-CID fonts. Now made uniform.
5. The Type 0 font matrix and the descendent CID font matrix were applied
in a wrong order in gdevpdte.c .
6. To satisfy (D2) when WMode 1 is only requested,
write DW 0 when WMode 1 is only requested.
7. After fixing all above, from the test file of the bug 687753 pdfwrite
generated a PDF, which GS failed interpret due to a curious failure
with e_dictfull while checking for an absent key /File in the font dictionary.
Patched zfcid1.c to provide a tolerance.

(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued 9).
Check the Encoding compatibility while merging Type 3 glyph variations.
DETAILS :
Fixes the reopened bug 687660
"incorrect font rendering/missing glyphs from ps2pdf".
pdf_is_same_charproc1 now checks whether we try to replace
a charproc with one taken from a font with a compatible Encoding.
Before now the encoding was ingnored,
causing a subsequent failure (due to an encoding conflict)
when adding glyphs to the font copy, and an infinite loop.
As usual, the encoding compatibility
is being checked within the list of characters of a current text.
EXPECTED DIFFERENCES :
None.
(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued 8).
Allocate a single character list per text.
DETAILS :
This change is algorithmically equivalent.
It's a preparation for fixing the reopened bug 687660
"incorrect font rendering/missing glyphs from ps2pdf".
For 1-byte fonts now we allocate a singe instance of
pdf_char_glyph_pairs_t for storing the character list for entire text.
Now it is done once per text as an extention to pdf_text_enum_t.
The intention is to provide an access to it from pdf_find_same_charproc.
CID text is still processed in chunks, which
are delimited by font changes or CDevProc callouts.
It may cause a searchability problem with some viewers,
when converting a composefont with a Type 3 descendent.
But unlikely we'll met such case in practice,
due to we have no exmples of composefont with a Type 3 descendent.
We would like to improve the CID text processing sometimes with
with building a complete character list for a text portion
delimited with font changes. The new algorithm for scan_cmap_text
should be like this : first delimit a single font portion,
then construct the character list for the portion,
and then process the portion with possible CDevProc and charproc callouts.

Fix : toolbin/pdfinflt.ps did not decompress some streams.
DETAILS :
Patch from SaGS for the bug 687746
"gs\toolbin\pdfinflt.ps doesn't unpack a stream"
Current version of pdfinflt.ps uncompresses only streams that have a single
filter applied, and only if that single filter is /FlateDecode. Proposed
patch (attached) ads support for procesing streams with multiple filters.
However, not all decompressing filters can be removed, and not in all cases
it would be desirable to remove them. The /filterstoremove dictionary lists
filters that are to be processed, and omits filters that are to be preserved
in the output. For streams with multiple filters chained together, the new
version of pdfinflt.ps removes all filters from the first in the
decompressing chain up to, but excluding, the first filter that is to be
preserved. The list of preserved filters, with the reason why these are not
removed, follows:
/RunLengthDecode, /CCITTFaxDecode, /DCTDecode:
These are normaly used for compressing raster images. I assume the main
purpose of this tool is to decompress page streams for debugging, and
decompressing images only adds a huge amount of binary data, making harder
to find and examine content streams. If this is not the case, and getting
raw image data is necessary, simply uncomment the lines corresponding to
these filters.
/JBIG2Decode, /JPXDecode:
There's no (standard) PostScript filter that corresponds to these PDF
filters. (I think) GhostScript implements these filters in the PostScript
interpreter, but not for all platforms, so I added some detection code for
them. The preceding paragraph applies too, so I left the lines corresponding
to these filters commented out.
/Crypt (PDF1.5-specific):
This is a generic interface with decryption plug-ins, and has no PostScript
counterpart (and I don't see how it could have one).
EXPECTED DIFFERENCES :
None.

Fix (pdfwrite, PDF interpreter) : Correctly handle different widths for same glyph (continued).
DETAILS :
This patch continues a long story about the handling of different widths for same glyph
in a PDF embedded font.
The last patch in this series was
http://www.ghostscript.com/pipermail/gs-cvs/2004-September/004834.html
That patch caused a problem with pdfwrite,
which needs to write an original glyph name
rather than a substituted one.
This change establish a new discipnile for
passing the original glyph name from the PDF interpreter to pdfwrite
inside a substituted glyph name, with using an
implementation specific separator (~GS~).
Before writing a font, we apply copied_drop_extension_glyphs
to remove extended glyph names. We don't like to
modify the font, but choose this minimal solution for now.
A better solution would be to introduce another flag to glyph slots
to mark ones, which to be skipped when writing the embedded font.

Fix LZWEncode filter to use the EarlyChange parameter and also correct the
tifflzw device to initialize EarlyChange to the proper value (1).
Bug 687726.
DETAILS:
The LZWEncode filter failed to use the EarlyChange param but the LZWDecode
did honor this setting. The LZWEncode always acted as if EarlyChange = 1
which since that was the default, worked as long as the Decoder wasn't set
for EarlyChange == 0.
Also, now that the Encoder honors EarlyChange = 0, the tifflzw device needed
to have the flag set correctly (it needs EarlyChange == 1).

Fix initialization of C stack streams that did not perform s_init().
Bug 687709 that could result in a Segmentation Fault (SEGV)
DETAILS:
The normal s_alloc() streams included s_init() on the allocated stream,
but C stack streams could have uninitialized elements in the stream struct.
Since this was UMR related, and affected the clist mode, the jpeg device
and the pswrite device (and possibly some pdfwrite data), this would be
different on different platforms.
The premature 'CloseTarget' action when the stream->close_strm was not
initialized as 0 (false) would show up as a SEGV when the -Z@ was used.

Fix for 687706 Display device 8-bit native incorrectly dithers grays.
This is a partial fix and also needs Dan Coby's fixes to the post
DeviceN halftoning. The DeviceRGBK color model is added.
DETAILS:
Prior to GS 8, the display device 8-bit native format would use 32
gray levels to avoid halftoning, and a 4x4x4 color cube which did use
halftoning. The halftoning logic was changed with the introduction
of DeviceN and in GS 8 both grays and colors were being halftoned.
The DeviceRGBK color model is added and used by the display device
native 8-bit format. The RGB color space to RGBK color model
conversion converts pure RGB grays to the K (black/gray additive)
component. This allows the 32 gray levels to be recognised by the
halftoning logic as being sufficient to avoid halftoning.
Fix for 687718 The tiffsep device fails when the size of gx_color_index is 32 bits
DETAILS:
The comments on bug 687705 "Compile of 8.31 fails on OS/2" point out that the
tiffsep device fails during device initialization if the size of
gx_color_index is 32 bits.
This is due to a recent change which made the default number of components for
this device equal to 8. This works if the size of gx_color_index is 64 bits.
But it fails with 32 bits.
This fix changes the default number of components for this device to be
based upon the size of gx_color_index. It also changes the psdcmyk device
to use the same logic for its default number of components.
This fix also includes changes to doc/Devices.htm which explains that the number
of components will differ based upon the size of gx_color_index (and a link
giving more details on gx_color_index). More information about the parameters
for the tiffsep device is given including an example command line.

This is a partial fix for 687706 Display device 8-bit native incorrectly
dithers grays. Russell Lang is improving the 8-bit (256 color) display
device to allow more shades of gray. This change is required for that
effort.
DETAILS:
The pre 8.00 release had more gray levels for the 8-bit display device
but the pre 8.00 release had other related problems in halftoning. The
fix for those problems eliminated the extra gray levels.
Russell's effort dug up some problems with the handling of halftones
for devices in which the max_color and max_gray values are different
and gray_index is set to an actual component number. This fix corrects
those problems.
Russell has a patch for the remainder of the effort. His changes
involve changing the 256 color display device to use a DeviceRGBK process
color model: red, green, blue and an additive black (gray). New
device color mapping procs also have been created for this process color
model. (This is the first example of this process color model in
Ghostscript.)

Fix (the filling algorithm) : Unite trapezoids if they have a common side.
DETAILS :
Bug 687716 "Assertion fails in gzspotan.c".
The spot analyzer can't reconstruct the topology when there are
two trapezoids with a common side.
We patched the spot decomposition algorithm with
uniting such trapezoids, because (1) it's too hard to
unite them in the "spotan" device, and (2)
the post-condition of the spot decomposer simplifies.
For more details see a new comment in code.
This patch causes a rendering difference.
We believe that a big part of differences happens due to the bug 687717,
which is currently unfixed due to the QA overload.
If the bug 687717 is fixed before this patch,
a small rendering difference can also appear,
because we unite trapezoids by the equality of x_current, x_next,
which have an arithmetic error. Therefore ununited trapezoids
may have a pixel center between them, which is not painted,
but shifting a boundary to x_current, x_next the pixel center
may fall into a trapezoid, then it is covered by the union and painted.
Besides that, with dropout prevention, a pixel set for the union of
two trapezoids may differ from the union of pixel sets for ununited trapezoids
when at least one of the trapezoids is narrow.
Particularly, two narrow trapezoids may paint 2 pixels,
but its (narrow) union does a single pixel.
Contacting trapesoids are not regular in characters,
which only use a dropout prevention,
but the test file of the bug 687698 (same as for 687667)
demonstrates some ones in a CJK TT font,
which composes hieroglyphs from subglyphs with a deformation and shifting.

Fix : Pattern metrics was imprecize.
DETAILS :
Bug 687581 "A pattern truncated".
This bug is a regression since the December 09 2003 revision.
We still think that we insufficiently understand the Adobe's method,
but now we've got one closer to CPSI than it was before the December 09 2003 revision.
Particularly the pattern step now appears better than on December 09 2003.
This patch includes a change, which is well defined by the math :
the usage of float2fixed_rounded instead float2fixed.
It is a part of the PRECISE_CURRENTPOINT stuff.
The rest of the patch is a kind of hewristic.
We guessed that a pattern size should always round up to allow
a similar logics as for a clipping - "any part of pixel inside".
As before December 09 2003, we improved the case with neither skewing nor rotation.
A further work on the general case may be useful.
At last, some old problems, which existed on December 09 2003,
are still unfixed. An example is -r300 298-09.ps :
a line appears outside the pattern box.
For now living them as they are, because
the primary purpose of this patch is to fix regressions.

Fix SEGV caused by premature free of the bbox device with high level
devices that use the bbox_device of the vector high level device.
Bug 687631.
DETAILS:
The vector device allocated a bbox device, but never incremented the
reference count past zero, so any use of the device that added a forwarding
device with that bbox_device as the target would free the bbox device
when that forwarding device closed. This happens with clipped images
or images that use ROP's since a clipping ROP forwarding could be used.

Add the LZWEncode filter that actually compresses using the LZW method,

that avoided the patent issues. Bug 687554.
Also fix a long standing issue in filter closing that failed to flush the
target stream after the final s_process_write_buf with 'last' == true.
Bug 224134.
DETAILS:
The LZWEncode filter was moved over from an older version of Ghostscript
that actually had a working LZWEncode.
The s_filter_close logic (discussed at length in bug 224134) was fixed
to be consistent with the specification and with Adobe. While the
target stream is not closed (per the specification unless CloseTarget is
true), the specification *DOES* call for an automatic 'flushfile' which
is supposed to be propagated down the filter chain.
Remove the 'makegnu' utility. It is out of date, and recent changes to
the documentation structure have rendered its automation more-or-less
unnecessary. The appropriate steps to convert releases are now
documented in doc/Release.htm.

CDevProc|Metrics|Metrics2 did not work with CIDFontType 0.
DETAILS :
Bug 687681 "Character spacing incorrect".
The old implementation, which comes from the gs-cjk team,
has a bug accessing the replaced metrics of a CIDFontType 0 font,
which effectively caused the replaced metric to be ignored with CIDFontType 0 fonts.
1. Bug : With CIDFontType 0, CDevProc|Metrics|Metrics2 was searched
in the descendent type 1 or 2 font rather than in the parent type 9 font.
1.1. A Type 9 font needs to be accessed via a descendent Type 1|2 font
in pfont->procs.glyph_info. Added a new field gs_type1_data_s::parent,
and provided an access through it with a new function gs_font_parent.
1.2. Metrics|Metrics2 is now accessed through gs_font_parent.
1.3. To access CDevProc implemented a new function zchar_get_CDevProc,
which also works through gs_font_parent.
1.4. gs_type1_data_s::parent needs to reset while a type 9 font finalization,
due to a reason, which we could not understand for sure.
Likely descendent fonts appear to have a bigger lifetime than
their parent type 9 font. Probably the descendents are pointed from
somewhere besides FDArray (maybe the font registry ?
or maybe after scaling the type 9 font from a type 9 copy ?),
and we think it's not good.
We believe that they should be released together with the type 9 font.
For now leaving it as it is, working around with a hack notify_remove_font_type9.
1.5. In stable font copies gs_type1_data_s::parent is set to NULL
to simplify the finalization. They are not used now.
2. Bug : In some cases the glyph bytecode was used instead the CID
as a key for searching a Metrics|Metrics2 element (zchar1.c).
3. Bug : The PDF interpreter wrongly scaled W,W2,DW,DW2 for CIDFontTYpe0 (pdf_font.ps).
4. pdfwrite : Improved the generation of W, W2 for CID fonts,
because after implementing (1) re-distilled 401-01.ps rendered incorrectly.
4.1. Prefer a non-zero width when computing DW, DW2 (gdevpdtw.c)
(debugged with 401-01.ps).
4.2. Don't skip zero W, W2 elements. The old code recognized zeros as
unused glyphs, but must do with the real glyph set in the font copy
(debugged with the test file of the bug 687681).
5. zcharstring_outline still ignores CDevProc. We believe that it is correct,
because it is used to compute font features with no dependence on
the relaced metrics.
6. pdfwrite : Allowed a CDevProc callout for CIDFontType 0, because
pdfwrite needs to know replaced widths, as well as it was done a half year ago
for CIDFontType2. Actually after implementing (1) pdfwrite stopped
to work correctly when re-distilling a PDF file with CIDFontType0,
due to now it uses W,W2,DW,DW2.
6.1. A new function z1_set_cache is defined for this purpose
similarly to zchar42_set_cache.
6.2. gs_font_procs::glyph_outline now retrieves the side bearing and width.
Added a new argument 'sbw' to all implementations.
6.2.1. Currently this function extension is implemented for charstring fonts only,
which need to interpret a charstring to retrieve the info :
type 1,2,9, because we don't want to run the type 1 interpreter 2 times
for getting sbw and bbox. Other font types retrieve zeros,
which currently are not used.
6.2.2. type1_cis_get_metrics has been made public.
7. We believe that the implementation of W,W2,DW,DW2 in the PDF interpreter,
which was contributed by the gs-cjk team, is unreasonably overcomplicated,
because it is based on CDevProc, which needs an interpreter callout,
which appears extremily hard from pdfwrite.
For now leaving it as it is (except a small improvement in (3)).
We would like to generate Metrics, Metrics2 instead that.
Note that a small part of this patch (the part (1)) is necessary
for generating Metrics, Metrics2 for CIDFontTYpe 0.

Partial fix for 687657 Text in transparency mask yields rangecheck in
discardtransparencymask.
DETAILS:
Three problems have been found with this file.
The rangecheck is actually a secondary effect. The actual problem
was a typecheck in setrgbcolor. However that error occurred inside
a stopped context.
1) The file has a mask group. This group specifies a color space (CS).
The previous code set the current color space to the given value.
However the FillColorSpace and StrokeColorSpace were not set. As a
result, a DeviceRGB color space was being used instead of the specified
DeviceGray color space. This resulted in a mismatch in the number
of operands when the color as set (1 versus 3). The fix consists of
setting both StrokeColorSpace and FillColorSpace when a mask group
contains a CS value.
2) The file uses scn for setting color values for a DeviceGray color
space. FillColor and StrokeColor can contain wither a single numeric
value (which is common but not required for DeviceGray) or an array
of values for all other color spaces. The scn and SCN operators were
always assuming that these values always contained arrays. The fix
consists of checking for the non array cases in the operators.
3) The appearance produced by Ghostscript with the test file does not
match Adobe. A solid magenta rectangle is produced by Ghostscript.
Adobe shows magenta text. This problem is NOT fixed by this patch.
Note: If the test file is opened with Illustrator CS and then saved,
Ghostscript does produced the same appearance as Adobe for the saved
file. The reason for the differences are not currently known. However
there are some more details in the bug report on this issue.

Fix for 687403 Poor halftoning for 16 color (4 bit) devices.
DETAILS:
This bug is a brother to bug 687390. That bug was for 256
color (8 bit) devices. Russell Lang suggested testing the 4 bit
devices and they were found to have problems caused by the same
logical error. The halftoning logic assumes that all components
for a device have the same number of shades. This was not true
for the implementations of the 4 and 8 bit color devices.
This fix converts the 16 color devices to using a 2x2x2 cube.
Note: A possible future enhancement would be to convert these
devices to using a 4 level gray for shades of pure gray (R = G
= B).
Fix for 687664 tiffsep sometimes producing apparently corrupt files
sometimes.
DETAILS:
The tiffsep device did not properly handle multiple page input files.
This change adds multiple page handling to the tiffsep device. Most
of the various tiff related routines already properly handled multiple
pages so changes were only required inside the tiffsep device.
The changes consists of:
1. Moving several variables which were local to tiffsep_print_page
into the tiffsep device structure and adding initialization. These
variables provide state information to the general tiff handling
routines and the file pointers for the separation files.
2. Add logic for determining if the output file name includes a
numeric format specification. If so then we create individual separation
files for each page. If not then we create a single file for each
separation.
3. A device close procedure was added to ensure that the separation
files were closed.

Fix (PDF interpreter) : Correctly handle different widths for same glyph.
DETAILS :
Bug 687672 "incorrect font rendering".
An Encoding may specify various character codes for same glyph, and
Widths may specify different widths for those codes.
Thus same glyph may be used with different widths.
This patch continues a long story about the handling of different widths for same glyph,
which includes my old hacks (pdf_font.ps Revision 1.22 and 1.26)
and Alex's change pdf_font.ps Revision 1.57 .
Alex defines new glyph names for same glyph to resolve the widths conflict.
After the Alex's change my old hacks appear low useful, and can be removed.
This patch
1. Removes the hacks;
2. Improves the Alex's change with the case when CharStrings has no referred glyph
(debugged with 1_2001.pdf)
3. Improves the Alex's change with minimizing a number of newly generated names,
because the test file of the bug 687672 maps many charcodes to .notdef with various widths.

Fix : A library context was not provided for bbox device.
DETAILS :
BBox device needs a library context for gs_next_id called from gx_image_enum_common_init.
It was not provided when the bbox device has no target.
We assume that the bbox device behavior doesn't depend on availability of a memory pointer -
likely it is so from reading the code.
Bug 687671 "epswriter it's not working at all."

A new implementation of shadings, step 87.
DETAILS :
Contrary to PLRM3 page 689, Background was not ignored with shfill.
Adding gs_pattern2_instance_s::shfill for that.
Bug 687673 "Axial shadings differ from Adobe".

A new implementation of shadings, step 86.
DETAILS :
1. Implemented gx_shade_background with a compatible INTERPATCH_PADDING logic
for filling a background.
2. The clipping logic in gdevdsha.c must be "any ppart of pixel inside",
as it is in other places.
3. Dont need adjust_swapped_boundary for clipping rectangles (gxshade6.c).
4. INTERPATCH_PADDING is enlarged to half pixel. See comment in code.
5. Optimized with a better clipping in gx_shade_trapezoid.
Completes the fix for 687585 "A shading renders narrower than its background".

Ignore MediaPosition when selecting a media type. Adobe CPSI does it this
way, and the PLRM suggests that this is advisory only. Bug 687547 for
customer 780.
DETAILS:
Adobe CPSI also ignores this parameter without generating any error or
warning. The PLRM says:
This parameter does not override the normal media selection process
described in the text, but if specified it will be honored�provided it can
satisfy the input media request in a manner consistent with normal media
selection�even if the media source it specifies is not the best available
match for the requested attributes.
Since an input PS file is unlikely to have a PPD that accurately reflects
the 'slot' numbers of our InputAttributes dictionary, we also ignore this
option and instead give the 'best fit' based on size and orientation (and
other parameters that may exist).

A new implementation of shadings, step 83.
DETAILS :
This is a partial fix for the bug
687585 "A shading renders narrower than its background".
It fixes various secondary problems :
1. gx_default_fill_linear_color_scanline could miss pixels at the end of the scanline
(bug 687585 "A shading renders narrower than its background", the right boundary).
2. decompose_linear_color could miss pixels when swapping axes of the clip rectangle.
(bug 687585 "A shading renders narrower than its background", the top boundary).
Defined adjust_swapped_boundary and applied for this purpose.
3. mesh_padding cauld miss pixels when swapping axes of the padding.
Defined adjust_swapped_boundary and applied for this purpose.
4. Moved the fill adjustment from gx_dc_pattern2_fill_path to gsshade.c
and disabled it in the NEW_SHADINGS build, because NEW_SHADINGS build never
needs it. Instead that it applies mesh_padding.
The new function gx_dc_pattern2_fill_path_adjusted access the new functionality
from outside gsshade6.c .
Also renamed gx_dc_pattern2_fill_path_adjusted with gx_dc_pattern2_fill_path
for a better reflection of its new purpose.
5. Implemented VD_TRACE_DOWN in try_device_linear_color.
The old code did a misleading drawing.
6. Fixed a conflict of the 's' flag in the -T argument.
Changed the documentation to reflect that.

Fix (Type 1 hinter) : A further improvement of the glyph rendering quality, step 1.
DETAILS :
This change is algorithmically equivalent,
because new code is disabled wirth configuration switches
listed below.
1. FINE_STEM_COMPLEXES
1.1. Stem complex could miss a common boundary.
1.2. Stem width could be distorsed due to a common boundary missing
(Bug 687578 "T1 hinter disturbs stem width".).
1.3. Overall hint (if presents) should have a bigger priority.
2. ALIGN_BY_STEM_MIDDLE
2.1. A stem middle could be shifted too much due to
independent grid-fitting of boundaries and the change 1.2 -
see 'i' in ccc-.pdf attached to Bug 687578.
Fixed with an improved alignment with t1_hinter__align_stem_to_grid.
2.2. This isn't applicable for top|bottom zones from the TT stem recognizer,
because we want to force outer boundaries to keep the glyph height.
2.3. 033-52-5873.pdf defines "pseodo-stem" hints,
which have only one boundary corresponding to real poles.
recognize them with t1_hinter__mark_existing_stems,
and don't apply the improved alignment,
because those stems designate outer glyph boundaries,
which we want to force the uniform glyph height.
Apparently fixes Bug 687579 "Type 1 hinter disturbs glyph height".

Add some job server related support. The -dJOBSERVER option defines the
^D to start a new encapsulated job, and the ^D is changed to be a self-
delimitting token in the scanner. Fixes 687079.
DETAILS:
For backward compatibility, -dNOOUTERSAVE is retained, but this does
*NOT* define the ^D to start a new encapsulated job. As specified in the
updates to doc/Use.htm, in order to avoid an /invalidrestore error,
the input should be from stdin otherwise the restore done as part of the
new job encapsulation (restore returns to the server state) will encounter
a file object that was created after the encapsulation save.
This allows 289-01.ps to complete IFF the -dJOBSERVER option is used
during regression testing. Thus the only (eventual) regression change
will be:

Fix for 687640 Unable to set default halftones for PDF.
DETAILS:
To support both PS level 1 and PS level 2 interpreting modes,
Ghostscript defines two routines for setting a default halftone.
PS level 1 does not support resources. Thus for PS 1 we have
.setdefaultscreen which sets a default halftone which is defined
inside of gs_init.ps. For PS 2, we have .setdefaulthalftone
which is similar to .setdefaultscreen except that it also checks
for a default halftone resource.
The PDF interpreter's handler for the /HT gstate parameter
called .setdefaultscreen if the parameter value was /Default.
This fix changes the handler to use .setdefaulthalftone instead.
This results in the PDF interpreter using the default halftone
resource if it is present.

The problem happened due to the PRECISE_CURRENTPOINT patch

Fix for 687607 Text missing with TextALphaBits=2 and tiffsep device.
DETAILS:
The TextAlphaBits and GraphicsAlphaBits device parameters were not working
for devices with a depth of more than 32 bits. The fix involves replacing
the copy_alpha device procs in the 40, 48, 56, and 64 bit memory devices
with the gx_default_copy_alpha routine. These devices previously had a

Fix half-toning for display device, bug 687629.
DETAILS:
Prior to DeviceN, dither_gray/max_gray were used if ncomp==1.
With DeviceN, dither_gray/max_gray are used if gray_index >= 0.
The display device was not correctly setting gray_index for
native 1-bit/pixel format.

Fix for image matrix having negative values. Thanks to Len Sorenson
for submitting this patch (author unknown). Bug #687411.
DETAILS:
The error is using floor to round a value without checking if it might
be negative first. There were actually two places that did this even
though the patch that was originally submitted only was for one of them.

Close the font file after the font has been processed (loaded into VM).
This prevents a problem with using up too many file handles detected on
Solaris. Thanks to Alex Cherepanov for the patch. Bug #687066.
DETAILS:
The patch has no effect on the cache. There is no point of not closing
the file after the content has been copied to memory.
On GNU/Linux GS has 250K VMThreshold and 1024 handles. That's enough.
On Windows GS has 1M VNThreshold and 512 handles. This is still OK.
On Solaris GS has 1M VMThreshold and 256 handles. Handles can be used up
before garbage collection starts. The following program fails on Solaris.
(a)(w) file closefile
1000 { (a)(r) file pop } repeat
Dependence on VMThreshold indicates that GC is not activated by
open(2) failing with EMFILE . This is a real bug, the patch is
just a work around that we may need to fix later, but not likely to
be a problem.

Fix to close streams at EOF (not only filter streams), as required by

DETAILS:
This is similar to a patch that I had developed and tested prior to
Alex's patch. I had tested my patch, then Alex's against the regression

Allow the display device row alignment to be changed from the
default 4 bytes to 8, 16, 32 or 64 bytes.
DETAILS:
If the image is allocated in video display memory, an alignment
such as 16 bytes (128-bit memory) may be required.
This is implemented by making the underlying memory device
use a larger width than the display device.

Changed iapi to use a void* instead of a gs_main_instance pointer.
Changed iapi to use a void* instead of a gs_main_instance pointer.
Cleaned up warning related to function pointer signature miss-matches.
DETAILS:
iapi.h no longer defines a type for gs_main_instance *
This will likely need to be put back in for backward compatibility.
The iapi interface now uses a void * instance handle reflecting
that it is an opaque type to the outside world.
Note that function pointer argument miss-matches generate warnings in
msvc but not in gcc. These have been fixed.
Enable progressive updates for the image window of
the MS-Windows ghostscript command line program.
Change update method to use a Windows timer.
DETAILS:
In the MS-Windows GUI executable (i.e. text window managed by
ghostscript rather than using a system console window), the image
window is progressively updated every second or so as each page
is drawn. The console executable did not do this.
The update code for both GUI and console executables is changed to
use a timer. The display update code is called whenever particular
device drawing operations happen, and if a timer is not already
running, it starts an update timer. The minimum update interval
is shortened from 1s to 100ms. The time to refresh the window is
measured, and the update interval may be increased to make sure
that updates account for no more than 10% of processing.
The update interval is decreased if subsequent updates are
much quicker. The timer is stopped by any sync.

Bug 687597 pdf created by pdfwrite has garbled text (spr 3994)
1. When a document embeds 2 fonts with same name, same hinting
and same glyph names but different charstrings, the old code
didn't compare charstrings and erroneusely merged fonts.

Implementation of 687496 transparency and CMYK support.
DETAILS:
This change extends our current implementation of the PDF 1.4
transparency to include blending in a DeviceCMYK color space.
There is also a partial implementation of a DeviceGray blending
space. However I do not have a method of generating test data
for a DeviceGray blending space. Currently the choice of a
blending color space is based upon the process color model of
the output device.
Note: There two differences expected in the regression testing.
These are with ai2.pdf and dina3_watermark.pdf.

Handle invalid PDF's that use 0.0 font scaling (Tf operator). Fixes bug
687606 for customer number 780.
DETAILS:
If the font scale is 0.0, then just use a very small value. This may result
in a small unwanted dot, but that is probably not an issue since it is
an invalid value. The better approach for 'invisible' text is to use
TextRenderingMode 3. The 'pdfformaterror' function is used to complain
about this so the problem might get fixed by the PDF Creator.

Fix bug 687038 that resulted in a crash if the initial device was not
pdfwrite.
DETAILS:
This was almost fixed by recent changes to gs_pdfwr.ps and
gs_setpd.ps for bugs 687325, 687436 and 687458.
Unfourtunately, the initialization of parameters only occurred
if the initial device was pdfwrite. A second patch removing
the initial device constraint on the '1010' .schedule_init
process was committed and fixes the problem.
Note that there was a work-around that if -dPDFSETTINGS=... was
given on the command line, it also worked.

Added memory_t pointers to gs_malloc() gs_free() calls in
devices that aren't normally built.
fixed bug with iapi, removed gs_lib_finit()'s call of gs_malloc_release.
DETAILS:
The problem is that single instance and multi instance interfaces
both call gs_to_exit() with different meanings.
If gs_lib_init0 was called then it should malloc_release
single instance exit library means free all.
If the iapi interface was used then the memory
should not be freed since gs_lib_finit() and gs_to_exit()
are called when the interpreter is exited but there is a
seperate delete_instance call that should free the memory

Windows only:
check_interrupts() with a mem pointer to access the poll function.
DETAILS :
This is windows specific since only windows uses the polling
function in check_interrupts() macros. If the gs_dll interface
is used then a single instance is forced since the design of that
interface forces one thread per process. The iapi interface can not
but enabled for more than one thread until the stream calling check_interrupts()
calls are fixed.
process_interrupts(NULL) calls are currently hacked to access a global memory
pointer intended for access to stderr. This is a place holder until the
stream object changed that guarantee a valid memory pointer in process_stream
calls are committed. Basically it is common to allocate a stream object on the
stack and use it in a functional manor with an uninitialized memory pointer in the
object.
gs_memory_t pointer additions for msvc build.
DETAILS :
Mostly gs_malloc() and gs_free() additions of a gs_memory_t argument.
Not gsdll.c forces a single instance.
Addition of a Library Context to start the process of removing globals.
DETAILS :
The goals is to remove globals from the system, this includes static
globals that would hinder multiple threads from running at once.
gs_lib_ctx is intended to be used as the opaque "handle" object
that a client would use to associate with a thread running through
the library. Independent of a gs or a language switch build, this
needs a new iapi2.h that allows the use of better job control from the
client side.
gs_lib_ctx is stashed under the gs_memory_t object and all memory objects
used by a thread refer to the same gs_lib_ctx. This storage location was
choosen as a convenence since a memory_t pointer is common throughout the
system. Most of the turmoil is adding memory_t pointers to functions that
used global variables but didn't have a memory pointer.
FILE stdin, stdout, stderr are one per process by default.
stdin and stdout may be changed but stderr may not.
FILE stderr is one per process and shouldn't be changed.
Note the stderr_fn is also one per process, changing this function pointer
will not help as most users of stderr printing do not have a thread handle.
Changing to a thread local storage mechanism can solve this.
gs_id's are currently per thread with each thread starting over at 1.
This can be moved to per process with mutexes if so desired.
A library context has a pointer to the top_of_system the intent is that this
a void handle avaliable to make top of the system calls without knowing the
data type. In a postscript only build this would be gs_main_instance but
in a language switched build this would be an object above that main_universe.
Other members of gs_lib_ctx_t are nothing more than global objects relocated
to this "bag". gs_name_table, dict_autoexpand are examples of this. There
are a few more globals that will be moved.
At the moment iapi is still constrained to one thread, since some of the
globals haven't been removed yet.
The display device's callback function setting is supported for now
but this interface should be changed to a sDEVICE style call.
gs_memory_t is the base type the abstract type gs_raw_memory_t is gone,
this means that all memory types must derive from gs_memory_t.
In addition to a pointer to the gs_lib_ctx there is a pointer to a
non_gc_memory this will always point to a non garbage collected memory,
it maybe the current object or an object below the current gargabe
collected memory space. This can be used were the previous code
used the global gs_malloc_memory. gs_malloc() now takes a memory pointer,
it finds the non-gc memory from a valid memory pointer and allocates from it.
The gdevbit device has an improved algorthym for converting from cmyk to rgb,
this is never used by postscript but for pcl rops it puts the k plane into rgb.
Add variable declaration for the path to the ghostscript executable to
the unix wrapper scripts. This simplifies changing the invocation name.
Partial fix for bug 686863.
Fix : .OrigFont was not provided when an embeded font is defined.
DETAILS :
Bug 687598 "Courier CE font problems".
The test case embeds a font with an instandard FontMatrix [ 0.00039 0 0 0.00039 0 0 ].
For passing it to pdfwrite, the procedure .completefont adds the
/.OrigFont key to the font dictionary. However the key was added after
.buildfont1 is called, and the device did not recieve the information at the time.
This patch moves the .OrigFont setting ahead to the .buildfont* call.

More work upon 687551 Implement the remaining TN 5044 procedures.
This commit implements the setcmykoverprint procedure.
DETAILS:
We received a posting against 687551. This posting indicated that some
files in arXiv.org were failing with the current version of Ghostscript
but worked with older versions. The files were all created by a package
called Canvas by Deneba Systems. They failed because setcmykoverprint
was not defined.
Evidently the people at Deneba Systems did not read the following comment
from page 15 of TN 5044:
"Note The setcmykoverprint operator has not been adopted by the industry.
It remains on the list of color convention operators because it has some
perceived usefulness, but it is not supported by any shipping host-based
separation applications today."
The even stranger detail is that the Deneba Systems people have a
dummy version of this procedure that does not implement overprinting.
Thus if they do not need overprinting, they have no need to use this
procedure.
The files also fail with Distiller 6.0, Illustrator CS, and Photoshop 6.0.
However this change allows these files to work with current Ghostscript.
The change consists of putting in a dummy version of the setcmykoverprint
procedure. This version does not actually implement overprinting.

1. Fix (PS interpreter) : The FontBBox validation check was too strong.
2. Fix (pdfwrite) : Explicitely set line parameters in a charproc.
DETAILS :
Bug 687594 "Barcode Width".
See comments in the new code.
This solution is a partial one.
With the current architecture of the Postscript interpreter,
a device can't recognize whether a PS charproc sets line parameters or not.
Therefore we copy to PDF the values, which appear at a first use
within a charproc. The old code copied only values, which differ from defaults.
The new behavior appears closer to Adobe Distiller.
A complete solution should copy the PS behavior to PDF,
i.e. the PDF charproc should set those and only those parameters,
which are set by the PS charproc. For doing that we need flags in the graphic state structure
per each graphic state parameter, reset all them before running a charproc,
and set whenever a parameter is changed. Without the flag, when the charproc sets
a value equal to the old one (which was inherited from the context of
the glyph usage), the event of setting is lost and causes a line width and other problems.
We don't want such a deep change now, and go with the partial solution,
because the partial solution appears enough for customer's needs.
Likely Adobe Distiller have same architectural problem, and resolves it in same manner.

Fix for 687572 AFPL Ghostscript 8.14 fails with some PDF files.
DETAILS:
The given file uses the scn operator inside of a form. The scn
operator is used for defining a color with DeviceN color spaces.
The scn operator uses .pdfcount (inside of scresolve) to determine
the number of parameters. However inside a form, there is an extra
dictionary on the stack.
The fix consists of adjusting pdfemptycount (which is used by .pdfcount)
to match the stack depth while executing a form. After the form is
executed, pdfemptycount is returned to its previous value.

ps2write step 37 : Don't convert Type 1 into CFF when generating ps2write output.
DETAILS :
1. Applied the Type 1 font writer.
2. Rather Type1C is a PDF 1.2 feature, we can't write it into a ps2write output.
We use the OrderResources parameter to decide about (not)converting Type 1
into Type1C (i.e. into CFF), because we want to write some PDF1.2 objects
into a ps2write output (for example - function objects,
because we don't want to convert them in C code).
3. The parameter OrderResources isn't a good switch for deciding about CFF
due to the parameter name, but currently we don't want to define one more parameter.
Maybe will improve it later.
4. Fixed a bug, which wrote "/Length1 -1" with Type1C.

Fix (pdfwrite) : Provide a delayed stream writing.
DETAILS :
The ps2write requires length of streams to be written before the stream.
This implements pdf_begin_data_stream with opening a stream object in a temporary file,
using a methgod similar to pdf_enter_substream.
With the new mechanizm the output file doesn't need to be positionable,
and the generated PDF appears more effective because the number of objects is smaller.
Also fixed a bug in gdevpdfu.c : crashed when encrypted with no page compression.
EXPECTED DIFFERENCES :

Fix (pdfwrite) : Discard the output file seekability requirement in the /PS pdfmark implementation.
DETAILS :

Now /PS pdfmark is implemented with pdf_enter_substream,
which writes the length directly into the object dictionary.

Fix to pdfwrite initialization to make sure initial distiller params are
incorporated into the device. Also add collection of distillerparams when
building currentpagedevice. Fixes bugs 687325, 687436 and 687458.
DETAILS:
Earlier change to use .putdeviceparamsonly in gs_pdfwr.ps so that the
use of setdistillerparams does not reinitialize the device caused the
initial parameter settings to not be set in the device. The change to
gs_pdfwr.ps accomplishes this.
Part of the investigation by Igor Melichev discovered that the values of
disillerparams would not be correctly reflected in the pagedevice. The
change to gs_setpd.ps collects the currentdistillerparams when the device
is pdfwrite and merges new values into the pagedevice dictionary. The
method is similar to that used for the dynamicppkeys such as PageCount
that can be changed by the device. For the distillerparams, the values
are changed dynamically by setdistillerparams.

Fixes bug 687451 "default resolution for display device"
Set the display resolution from the MS-Windows display resolution,
using a device parameter -dDisplayResolution=DPI.
DETAILS:
The initial resolution must be set in display_put_params.
Setting it in display_open is too late because this leaves
the device resolution and currentpagedevice reporting
different values. Callbacks can't be used in display_put_params
because the callback structure is not yet initialized.
This leaves a device parameter on the command line as
the cleanest implementation.
If HWResolution is set (e.g. from -r72), then use that.
Otherwise, if DisplayResolution is set, use that in the
initial display_put_params. After that, ignore all further
use of DisplayResolution.
The Windows client adds -dDisplayResolution=DPI to the
command lines, similar to the existing -dDisplayFormat.
The Windows client gets the resolution from the GDI.
The default Windows display resolution is 96dpi (the same
as the display device). This can be changed to 120dpi by
selecting "large fonts", or other values in recent versions
of Windows.
Fixes bug 687562 "vector devices close output file incorrectly".
Vector devices open the output file with gx_device_open_output_file,
so should close it with gx_device_close_output_file, not fclose.
This was preventing pswrite from correctly closing special
files such as "%printer%Printer Name" on Windows and OS/2.

In the Windows %printer% IODevice, the existing thread handle
is closed automatically when the thread finishes. Duplicate
the thread handle so we always have a valid handle for waiting
and closing.
DETAILS:
When the thread finishes, the CRTL _endthread is closing
the existing handle. During debugging, it was found that
waiting on the thread handle was Ok because the thread
was still running, but by the time CloseHandle ran the
thread handle was invalid.
IODevices are effectively static, so iodev->state is initialized
once at the start of the interpreter. There is no need to
test if iodev->state is valid.

Fix for 687565 Incorrect equiv color for Orange in Altona test file.
The altona test file Altona_Visual_bb_1v1_x3.pdf contains a spot color
called Orange. An incorrect equivalent CMYK color is being determined for
this spot color. The result is that the spot color is being displayed as
black for the devices which handle spot colors and attempt to determine
equivalent CMYK colors for the spot colors. These are the psdcmyk,
tiffsep, and display (with -dDisplayFormat=16#a0800) devices.
DETAILS:
The Orange spot color is used in two different DeviceN color spaces. The
first color space has components named 'None'. These components are used
as part of a special feature described in section 4.5 of the PDF 1.5 spec.
This feature uses the None components as a means for passing values to
the color space's alternate tint transform function. In the example in
the spec., these values are an equivalent color in the alternate color
space.
Our logic for determining an equivalent CMYK color for a spot colorant
sets all color components except for the desired spot color to zero and
then uses the tint transform function to form an alternate color. This
results in the equivalent CMYK color being black since the None values
contain the real information for the tint transform function.
This change consists of check for the presence of DeviceN color space
components named None. If any are detected then the equivalent CMYK
color logic exits rather than determine an invalid color. This is
sufficient for this case since the second color space which contains
the Orange spot color does not have the None components. For the
general case, a solution needs to be found which samples colors given
actual values for the None components.

Log Message:
Fixes bug 686956 Display device does not support separations.
Add support for separations to display device.
This requires a change to the display callback structure.
Support is maintained for clients using version 1 of the structure.
DETAILS:
Add support for a new color format, DISPLAY_COLORS_SEPARATION,
which supports CMYK and spot colors. A new callback
display_separation() is used to tell the client about
the names and CMYK equivalents of each separation.
The callback structure version number is incremented to 2
to show that has changed. The display devices checks
whether it is passed the older v1 structure or the newer
v2 structure, and only calls the new separation callback
if it was given a v2 structure.
Only 8-bit/pixel, up to 8 components and 64-bit depth are supported.
In the Windows and gtk+ clients, a subset of these 8 separations
can be selected for display.

charproc_just_accumulated was not properly initialized on some circumstances.
EXPECTED DIFFERENCES :
Bug687546.ps (new)
This change creates common routines for handling the DeviceN related
device parameters (SeparationColorNames, SeparationOrder, and
MaxSeparations). The change also splits up some common routines that
were assuming that the device was a 'printer' device.
Fixes nonportable code in the vasarely.ps example file so that keeps
to reasonable page size values even when default clippath is very
large (as is the case with the bbox device). Fixes bug #687549.

Fix (pdsfwrite) : Compression of XObjects implicitely depended on CompressFonts.
DETAILS :
This patch makes the dependence explicit.
Have no idea which distiller parameter must controll patterns and forms,
so keeping the old dependence.
With OrderResources=true pages now depend on CompressPages.
EXPECTED DIFFERENCES :
None.
ps2write part 2 : Delay writing pages.
DETAILS :
The new code is disabled with PS2WRITE 0 in gdevvec.h .
With OrderResources=true it writes pages at the end of the document,
after all resources are written to PDF.
Before that pages are accumulated in a temporary file.
OrderResources has been moved from distiller parameters to device parameters.
EXPECTED DIFFERENCES :
None.
ps2write part 1 : starting the project.
DETAILS :
Define a new temporary configuration switch PS2WRITE.
The new code is disabled with PS2WRITE 0 in gdevvec.h .
Our development strategy is to make pdfwrite to generate an output,
which a PS interpreter can handle with a special procset.
For a while we'll not define a new ps2write device,
but enhance the pdfwrite device with a new feature.
A new temporary distiller parameter OrderResources will make pdfwrite
to keep a proper resource ordering for generating a PS output.

Fix for 687553 rangecheck in .sethalftone5 and SeparationOrder.
DETAILS:
If a file specifies a type 5 halftone and the SeparationOrder device
parameter is specified then a rangecheck can occur. This happens when
the halftone includes two or more colorants that are not in the
SeparationOrder parameter or one colorant and a 'Default' value.
The problem occurs because the get_color_comp_index device procs use
GX_DEVICE_COLOR_MAX_COMPONENTS to indicate colorants which are not
being imaged due to the colorant not be included in the list for the
SeparationOrder device parameter. However the
gs_color_name_component_number routine was using the same value to
indicate 'Default' halftones.
The fix consists of modifying gs_color_name_component_number to look
for GX_DEVICE_COLOR_MAX_COMPONENTS from the get_color_comp_index
device proc. If found then the component is treated the same as
a component that is not present in the device. The halftoning
logic is only concerned with the colorants which are actually being
used by the device.

Change the default handling of the MaxSeparations device parameter. This
parameter is only used by some of the DeviceN mode devices (which have
their own handling of this parameter). The default handler now simply
ignores this parameter. However it does read the parameter. Not reading
the parameter was causing problems with PDF files and page devices.

This change implements the enhancements described in 542629 CMYK
tiff driver and 687440 Support for outputting PDF separations
separately. This change implements three devices: tiffgray
which produces an 8 bit gray output with uncompressed data,
tiff32nc which produces 32 bit CMYK with uncompressed data, and
tiffsep which produces a tiffgray file for each separation
(CMYK and spot colors) and it also produces a CMYK output file
which is created using the CMYK image data plus the spot
colors image data. The spot colors are converted to CMYK using
the logic in 687431.
DETAILS:
This change requires that 687504 be included in the sources.
The tiffgray and tiff32nc devices are logically similar to the
tiff24nc device except for the use of gray and CMYK process
color models.
The tiffsep device uses much of the logic which has been created
for the psdcmyk and spotcmyk devices. These include logic for
implementing the SeparationOrder setpagedevice parameter 687423,
logic for determining an equivalent CMYK color to spot colors
687431, and automatically detecting spot colors (without requiring
that they be specified via the SeparationColorNames setpagedevice
parameter 687504.
The tiffsep device also prints the names of any spot colors
detected within a document to stderr. (stderr is also use for the
output from the bbox device.) For each spot color the name of
the color is printed preceded by '%%SeparationName: '. This
provides a mechanism for external applications to be informed about
the names of spot colors with a document.
Due to the 64 bit pixel size limitation, the tiffsep can handle
a maximum of 8 colorants per pass. However it is possible to
handle more than 8 colorants by doing multiple passes. For each
pass after the first one, the names of all of the separations need
to be specified via the SeparationColorNames parameter and the
names of the desired separations need to be specified via the
SeparationOrder parameter. When colorants are selected via the
SeparationOrder parameter, the composite CMYK output contains
the equivalent CMYK data only from the selected colorants. It is
possible to create an overall CMYK composite for more than 8
colorants by then adding together (via an external application like
imagemagick) the composite CMYK output files from the individual
Ghostscript passes.
Internally each spot color is assigned a spot color number. These
numbers start with 0 for the first spot color. The spot color
numbers are assigned in the same order as the names are printed to
stderr (see above). This order also matches the ordering in the
SeparationColorNames list, if this parameter is specified. The
spot color numbers are not affected by the SeparationOrder parameter.
This device creates multiple output files. The file specified
via the OutputFile command line parameter is used to contain the
composite CMYK equivalent. File names for the separations for the
CMYK planes are created by appending '.Cyan.tif', '.Magenta.tif'
'.Yellow.tif' or '.Black.tif' to the to the end of the file name
specified via the OutputFile parameter. File names for the spot
color separation files are created by appending '.sn.tif' (where n
is the spot color number) to the end of the file name specified via
the OutputFile parameter.
The src/gdevtsep.c source file does have a compile time option for
including/not the '.tif' at the end of the created file name. It
also has a compile time option for using the name of the spot color
as part of the file name. However this is not enabled since there
may be conflicts with spot color names (in which Adobe allows almost
anything) and the operating system's conventions on file naming.
This change consists of the new source module src/gdevtsep.c,
changes to devs.mak for defining the new devices, changes to the
various top level make files for including these devices in their
DEVICE_DEVS definitions, and changes to the documentation files.
A new implementation of shadings, step 80.

Fix for 687534 Unable to determine equivalent CMYK for spot colors
that are only used with overprint.
DETAILS:
The given test file uses spot colors. However the psdcmyk device
was creating output files which did not contain equivalent CMYK
colors for the spot colors. The cause was that the previous
version of the logic was capturing the equivalent CMYK colors
when the psdcmyk device's high drawing procs were called. However
if overprinting is enabled, then the overprint device was inserting
its own versions of these routines. Since it only took one call
to a high level drawing handler, the previous logic would capture
the equivalent CMYK colors if there were any drawing operations
with a spot color that did not have overprinting enabled.
The fix consists of moving the capturing of the equivalent CMYK
colors to a new device proc. This new device proc is called
update_spot_equivalent_colors. This device proc is called whenever
a Separation or a DeviceN color space is installed.
The default version of the proc does nothing. Thus there is only
a small amount of overhead added for the installation of Separation
and DeviceN color spaces for devices which do not need the equivalent
CMYK colors for spot colors.
Most of the change consists of the standard details of adding a
new device proc. There are several places that have to be updated
when this is done. The documentation in doc/Drivers.htm was updated
to include this new proc. The high level drawing handlers in the
psdcmyk devices were removed and a new psd_update_spot_equivalent_colors
procedure was added. Some minor changes were made in the logic in
gsequivc.c since it is no longer necessary to scan through base and
alternate color spaces looking for Separation and DeviceN color spaces.
The comments at the beginning of gsequivc.c was changed to reflect
the changes in the logic for capturing equivalent CMYK colors for
spot colors.
Minor change to avoid a spurious compiler warning about 't' used before
initialized. Fixes bug #687412.
DETAILS:
This is an invalid warning, since 't' is always initialized before use,
however the extensive use of macros confuses some compilers. IMO, this
is an abuse of macros, but this is endemic in the older GS code.

687504 Enhancement: Imaging spot colors without using the
SeparationColorNames parameter.
DETAILS:
The purpose of this enhancement is to provide an example of how
to implement imaging spot colors without requiring that they be
specified in advance via the SeparationColorNames setpagedevice
parameter. Note: Spot colors are only supported on a few devices
which have output file formats which allow for spot colors. These
are currently the psdcmyk, spotcmyk, and xcfcmyk devices.
This commit only implements this feature on the psdcmyk, spotcmyk
and devicen devices.
In order to implement this feature, a device needs to be able to
allocate image buffer memory for each colorant and to detect when
a new colorant is being used inside of a color space. The
implementation has the following pieces:
1. The handling of the MaxSeparation setpagedevice parameter was
extended. Previously this parameter was always set to one. For
most devices it now indicates the number of colorants being used
by the device. For most devices this is a fixed quantity, however
for the psdcmyk device, this parameter can be used to tell the
device to allocate image buffer memory for up to eight colorants.
(The eight colorant limit is due to the fact that the psdcmyk
device uses 8 bits per colorant and we currently have a 64 bit
maximum pixel size.)
2. The devices already have a 'get_color_comp_index' routine which
is used to query if a colorant is supported by the device. However
this routine is used for both real components in color spaces and also
for some special cases. For instance, the same halftone may be used
either for a cyan or a red colorant. To handle this case, the halftoning
setup logic will query the get_color_comp_index routine to check if
cyan is supported by the device. If not then a query is made to see
if the device supports red. By monitoring the names of the components
passed to get_color_comp_index routine, a device can detect when a new spot
color is being used. However it is necessary to be able to detect
the special cases so that the device does not believe that it has a
'red' spot color. To do this the third parameter of the
get_color_comp_index device proc was logically modified to indicate
if a name represents a name actually in a color space or one of the
special case situations. Previously this parameter was not being used.
3. The get_color_comp_index routine for the psdcmyk device was
modified to look for new spot colors and to add then to its list of
colorants if there was space available. Note: This also required
that the psdcmyk device have its own structure descriptor, pointer
enumeration and relocation procedures. The macro which was used to
define the psdcmyk and psdrgb devices needed to be changed since the
previous macro used the st_device_printer structure descriptor instead
of the new structure descriptor for the psd devices.

Fix (type 1 hinter) :

2. Improve the unaligned pole interpolation;
3. Set a waeaker angle threshold in t1_hinter__is_stem_hint_applicable.
4. Allow an offset fuzz in t1_hinter__is_stem_hint_applicable.
5. Align upper/lower horizontal stems by the upper/lower edge.
6. A dependency was missed in lib.mak .
DETAILS :
Bug 687419 "poor font rendering on X11 with gs 8.14".
The intention of this change is to improve the rendering quality
with TextAlphaBits > 1, but actually it modifies glyph rendering in all cases.
1.
The test file of the bug 687419 shows that we had 3
inconsistent requirements :
- the analigned glyph origin;
- uniform glyph size;
- and contrast stems.
Since an uniform glyph height looks critical,
we drop the analygned Y-coordinate of the glyph origin.
In other words, now we ever align
the Y-coordinate of the glyph origin to pixels.
This also reduces the number of glyph raster variants in the cache.
2.
The old interpolation algorithm could cause
significant distortions with flex-like serifs, which are not marked with flex.
The character 'L' in the test document of the bug 687419 demonstrates that.
If the path goes outside the interpolation interval
and have no turns, now we shift the "outer" parts rather than
breaking the path at extremal poles. (We wanted this change
a long ago but haven't got a strong reason for it.)
3.
The threshold in t1_hinter__is_stem_hint_applicable changed from
1/3 to 9/10. This makes more stems to recognize. The reason for that
is the same character "L".
4.
Allowed a blue_fuzz offset t1_hinter__is_stem_hint_applicable.
Debugged with comparefiles/tpc2.ps .
5. In the test file of the bug 687419 the small font has no
upper alignment zone for lowercase. This caused an uniform glyph height
due to wide and norrow horizontal stems aligned ocasionally
by top or bottom. Implemented a choice of the aligned edge
depending on the Y-coordinate of stem middle relative to
the glyph middle.
6. gxhintn_h was defined in lib.mak after it is used at once.
EXPECTED DIFFERENCES :
Almost all comparefiles render differently.
Fix (pdfwrite) : Merge equal ExtGState objects.

Bug 687487 "(pdfwrite) redundant ExtGState objects".
Now we represent ExtGState objects as cos_dict_t instances,

Redundant equal objects are being substituted and skipped.
This patch consists of 4 parts :
1. Creting an ExtGstate object, replaced old calls to stream functions
with calls to cos_dict_t functions.
2. Implemented the comparizon/substitution logic in pdf_end_gstate.
3. pdf_prepare_drawing now doesn't pass keys to
pdf_update_halftone, pdf_update_transfer, pdf_write_transfer_map,
because we don't want them to become a part of a value.
Instead that we made them to be keys of the cos_dict_t instance.
4. Defined new functions cos_dict_put_c_key_bool and cos_dict_put_string_copy
to simplify the new code.

2. The update had an xref table with two entries. One of them
was bad. (Not a very good percentage.) To fix this problem,
all entries in the composite xref table are scanned to verify that
they point to a valid objects. If not then the rebuild logic is
used to attempt to recover the xref data. This can be disabled
by adding -dNoVerifyXref to the command line. In most cases,
the verification time is not noticeable but I did find a file with
104,000 xref entries and it took about 2 seconds to verify the
xref table.

(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued 2).
DETAILS :
This is a final step of fixing the bug 687489
"pdfwrite creates invalid Type3 font -- missing characters".
This patch provides a check whether a color was changed while
a PS charproc interpretation. A color command is written
into the PDF charproc if and only if the PS charproc changed the color.
This patch discovers a bug in Adobe Acrobat Reader 5 :
with the test document of the bug 687489 it paints an "invisible" text in the 4th page.
That text isn't visible when viewing with Adobe reader 6 and with GS.
The text is painted with a white color, but AR 5 erroneusly paints it with black.
EXPECTED DIFFERENCES :
None.
High level devices may need a device color while executing stringwidth.
DETAILS :
This is second step of fixing the bug 687489
"pdfwrite creates invalid Type3 font -- missing characters".
The problem happens due to the old code could run a charproc while
executing a stringwidth, when device color is not evaluated.
This patch provides the device color loading with no dependence
on the text operation.
dev_proc(dev, text_begin) now receives a device color in any case.
THIS IS AN INCOMPATIBLE CHANGE : if an old device depends on
a device color ability, it will malfunction.

(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued).
DETAILS :
This is a preparation for fixing the bug 687489
"pdfwrite creates invalid Type3 font -- missing characters".
The problem happens due to the old code could run a charproc while
executing a stringwidth, when the PDF viewer state isn't syncronized
with the PS graphic state.
We don't synchronize in this case because stringwidth doesn't paint.
Our intention is to know whether a charproc changes graphic state parameters :
current color, line width, etc. For doing so we need
(1) to save the viewer state in the viewer state stack,
and then (2) synchronize with the PS graphic state without
writing commands to the PDF. This patch does provide (1)
but does not implement (2) because we want to check
the change (1) for no regressions.
The change (2) will be a separate step.
Saving a viewer state in a stack when entering a charproc
was contributed with the recent patch
http://www.ghostscript.com/pipermail/gs-cvs/2004-May/004507.html
as an improvement of pdf_enter_substream, which was called from
pdf_install_charproc_accum called from pdf_text_set_cache.
In other words, the viewer state saving was deferred until setcachedevice/setcharwidth.
However we need to save the viewer state in the beginning of a PS charproc.
This patch moves the call to pdf_enter_substream from pdf_install_charproc_accum
to the TEXT_PROCESS_RENDER branch of pdf_text_process.
We believe that the new logic is more straight :
we start the charproc stream accumulation immediately before the PS interpreter
enters a charproc interpretation.
Minor changes :
1. Defined pdf_start_charproc_accum as a symmetric one for pdf_end_charproc_accum.
2. Renamed pdf_install_charproc_accum into pdf_set_charproc_attrs.
3. Improved the argument list of pdf_prepare_text_drawing.

Enable separable_and_linear and separable for the display device.
Fixes bug #687442.
DETAILS:
Enable separable_and_linear for gray, RGB and CMYK formats.
The display device needs to explicitly call check_device_separable
because it is closed and reopened when the callback is set,
which causes linear_and_separable to be reset.
Set the gray_index which is not set by check_device_separable.
Prevent the unimplemented DISPLAY_ALPHA_FIRST and
DISPLAY_ALPHA_LAST from being used.
Make it clear that the display_map_rgb_color_rgb and

(pdfwrite) : 1. Implementing a dynamic recongnition for Type 3 charproc variations;
2. Bug : Viewer state could desynchronize when entering a charproc accumulation.
DETAILS :
Bug 687472 "barcode wrongly converted to type3 font".
Type 3 glyph variations may appear if BuildChar uses setcharwidth.
If a charproc uses setcharwidth, we perform the charproc accumulation
for each character occurance, and compare the accumulated stream with older
ones if they exist. In the case of exact equality
(including the character name and character code),
the old charproc is used. Othervise we embed a new one.
If the character code was used with another charproc,
we create another PDF font to resolve the conflict.
Thus a single PS Type 3 font may convert into several
PDF Type 3 fonts, and the text may be broken into smaller pieces.
Particularly this happens with the test file of the bug 687472.
Viewers must account that implementing the text serchability.
A new array pdfont->u.simple.s.type3.cached is used to remember whether
a charproc uses setcachedevice[2]. If a character used it at ones,
we assume that all further its occurances to do same.
We think that this assumption is implied by PLRM.
Viewer state was not saved when entering a charproc accumulation,
and was not restored after exiting it (a bug).
This could cause wrong object attributes
and excessive commands written into PDF.
This patch fixes that.
Some PDFs become longer due to excessive ExtGState objects
generated for dropped copies of charprocs.
Opened a new bug 687487 for tracking this issue.

which may appear if BuildChar uses setcharwidth.
For the case of no error while charproc accumulation
this change should be algorithmically equivalent.
EXPECTED DIFFERENCES :

Handle some errors that could halt the regression run.
DETAILS:
When running a raster comparison, the test case generates a ShortDescription
that includes the modification date of the baseline raster date. If no such
file exists, the baseline gs is run to create an entry. However, if that
insertion attempt fails, there is no baseline raster for reference. While
the test case itself handled this properly, the ShortDescription logic did
not, throwing an error that terminated the whole run.
Also, makesum was returning '0' instead of None on failure, which was
incompatible with the use of its return value as a dbm key. It now
returns None in that case, and when it cannot stat the file argument
at all.
Fix reference count of overprint compositor so that it doesn't get freed
too early. Fixes SEGV of bug #687425 for customer #1110.
DETAILS:
This only showed up when banding was being used.
This only showed up when a high level image was being rendered from the
clist since this installed a 'clipper' device on top of the overprint
compositor. When the clipper device was closed, the finalization proc
decremented the reference count for the 'target' device of the clipper
which was the overprint compositor. When the overprint reference count
was decremented to 0, it was freed even though it was being used by
the clist renderer.

Log message:
Revised fix for 687418 WTS does not work with bitcmyk driver.
DETAILS:
The changes in this revised fix are pretty extensive. Note: This
patch includes several items from Russell Lang. I am including these
since they are required for the proper execution of the patch and
it does not seem reasonable to require possible testers or reviewers
to have to track down and install these patches separately.
The list of changes includes:
1. Added logic to check_device_separable to also set the gray_index
value. This suggestion came from Russell Lang.
2. Add verification that a colorants bits are consecutive. (from
Russell Lang in:
http://www.ghostscript.com/pipermail/gs-code-review/2004-May/004501.html
3. Changes to gx_default_encode_color and gx_default_decode_color
to use position and bit count info from the device's color_info data.
(Also from Russell Lang in the previously mentioned submission.)
(See the comments in item 21 below about the gx_default_decode_color
routine.)
4. Included test routines. (Also from Russell Lang in the previously
mentioned submission.)
5. Added calls to check_device_separable prior to calls to the
various 'fill_in_procs' routines (gx_device_fill_in_procs,
gx_forward_fill_in_procs, fill_in_procs). The fill_in_procs routines
use the separable information in choosing default routines for
the encode_color and decode_color routines. Thus we have a chicken
and egg problem since check_device_separable also uses the device's
encode_color routine. The test routines from Russell were a great
help in debugging
Also various changes that were found while testing this patch:
6. The various color deskjet drivers (gdevcdj.c) was incorrectly setting
the dither_grays and dither_colors values to 5 instead of 256. (I
have no idea why.) The max_gray and max_color values were set to
being set correctly to 255.
7. The color deskjet devices (gdevcdj.c) were doing BG and UCR
removal inside of the encode_color routines. These devices use the
default color_mapping_procs which also do these tasks. The code in
the encode_color_routine was removed since it could cause conflicts
with the overprint routines. The code in the encode_color routine
was also using a fixed BG/UCR logic (from PS level 2).
8. Corrected a problem in the color desk jet decode_color routine
which was always returning zero for the black value.
9. Changed the casting for values assigned to the std_colorant_names
field. Note: MSVC and gcc complain about different conditions.
There does not seem to be a combination that will keep both happy.
This set produces no complaints from gcc.
10. Corrected the setting of dither_grays and dither_colors for the
devicen device. Previously this was being set to 1 when it should have
been set to 256. Found by Russell Lang.
11. Modified check_device_separable to only check for appropriate
values of the max_gray/dither_grays and max_color/dither_colors
pairs only for gray/color devices.
12. Added check for encode_color routines which encode zero
bits for a colorant. Previously this condition would have caused
an infinitely in check_device_separable. Change suggested by
Russell Lang.
13. Removed a previous call to set_linear_color_bits_mask_shift
in gx_default_fill_in_procs. This has been logically replaced by
the calls to check_device_separable which have been added.
14. Corrected a problem in the ppm_map_rgb_color in gdevpbm.c.
This routine was calling gx_default_encode_color which requires
15. Corrected problem in pcx256 device which incorrectly setting
the dither_grays and dither_colors values.
16. Removed the check_process_color_names routine from gdevpsd.c
since it not used.
17. Modified the dci_alpha_values macro in gxdevcli.h. This
macro was setting some devices as 'separable' but was not setting
the related color_info fields (comp_shift, comp_bits, comp_mask).
Now this macro sets a devices as 'unknown'. The check_device_separable
routine will change this for devices which are separable. Devices
which want to change their process color model need to either set
themselves as 'unknown' and let check_device_separable handle things
or else the device needs to setup its own values for separable
color_info fields.
18. Added a call to check_device_separable into gdev_x_open in
gdevxini.c. With this addition, the x11 device is detected as being
sperable. This is need since the x11 device sets up a color map in
gdev_x_open. Prior to this, the encode_color routine for he x11 device
returns 0 regardless of its input.
19. Modified the uniprint device (gdevupd.c) and color laser jet
devices (gdevcljc.) to use 256 instead of 5 for its dither_gray and
dither_color values with devices that have 8 bits per colorant. This
is appropriate since the the max_gray and max_color values are 255.
(I do not know why these values were being set to 5. This same error
was found in gdevcdj.c. My only guess is that it was a typo in gdevcdj.c.
Since this device is recommended as an example of how to code a color
raster device (in Devices.htm), the error was propogated into the
other devices.
20. Added more comments to gxdevcli.h explaining the use of the
gray_index, max_gray, dither_grays, max_color, and dither_colors
fields in the device color_info structure.
21. Changed the gx_default_decode_color routine (again). Russell
Lang created two revisions to this routine as part of his efforts on
this task. However one version was slow but produced the desired
results. The second version was faster but its output was slightly
different. This revision produces the same output as the first
version but does so without the while loops that slowed its operation.
Note: There is another related submission from Russell Lang that is
not included in this patch. This consists of changes to the display
device for making it 'separable'. This change is needed for Igor's
linear shading work.

Apply a recursive 'configure' step to the autoconf build to generate
required code for the jasper library.
DETAILS:
The jasper library also ships with an autoconf build framework for POSIX
systems. Unfortunately, it relies on this framework to generate a header
file with defines describing the local system. This header, located in
jasper/src/libjasper/include/jas_config.h can be generated by hand from
the jas_config.h.in template, but it must be available when we're directly
compiling the source as part of Ghostscript.
We could attempt to construct one of our own, but within the confines
of an autoconf build, using jasper's native configure is more robust.
We could also go ahead and use recursive make to build the library
natively, but we would need a static makefile for non-autoconf builds.
Jasper provides an alternate header, jas_config2.h for use with MSVC.

2. mesh_padding and wedges with zero length sides were tested.
3. Skipped painting outside the clipping area.
4. Optimized for constant color.

A new implementation of shadings, step 73.
DETAILS :
The new code is disabled with NEW_RADIAL_SHADINGS in gxshade4.h .
The old implementation of the radial shading extensions appears
incompatible with the tensor representation of the radial shading
due to different spatial subdivision. Collisions at extension
boundaries caused dropouts.
Besides that, the old implementation
can't handle the case in which circles contact each another and one
circle is inside another. Also we suspect that with the old implementation
the trailing extension can overlap the shading when represented as "triangles".
This patch implements extensions with tensor patches.
Rather they have a constant color, we need the wedge logics
to work with them. Also we reworked the analyzis of
special cases of mutual placement of the base circles.
The new code works, but there are known problems :
1. Extensions to be tested systematically.
2. Debug mesh_padding and wedges with zero length sides.
3. Skip painting outside the clipping area.
4. Optimize for constant color.
5. Why "STEUER-RollingMesh 2(radial).ai-.pdf" generates so many triangles ?

and add ifdef's.
Partial fix for bug 687441.
[DETAILS]
Although nmake overrides internal definitions when called from command line,
it doesn't do so when the makefile is invoked from Development Studio.
GCC with -ffast-math compiles ang/90. as ang*(1/90.), losing precission.
This doesn't happen when the numeral is replaced with a non-const variable.
So we define the variable to work around the GCC problem.

Limit the number of timing runs we're willing to do to detect the cache
size, preventing an infinite loop if the os timing calls never measure
appreciable elapsed time. After a patch from Patrick TJ McPhee. Bug 687095.
DETAILS:
It looks like there's a bug in some versions of FreeBSD which cause
time_clear() to always return 0, even though the loop is being run.
This is clearly incorrect behaviour of clock() on these systems,
or the user is mistaken in debugging the problem, since we've been
unable to reproduce. But in either case our code is arguably wrong.
The later measurements will obviously not detect a nonlinearity if
the timing loop continues to return 0. However, they will terminate
at MAX_BLOCK (4MB) and so the misdetection isn't egregious. It was
only the estimation of the measurement error that could loop forever.

Fix for 687455. The overprint logic creates a temporary device which is
used to initialize a set of procedures. This temp device is only paritally
initialized. The partially initialized device is being set up as a

a problem when check_device_separable executed. This change sets the temp
device to 'not separable' so check_device_separable does not try to do

Fix for 687418 WTS does not work with bitcmyk driver. This fix
is applicable to most devices.
DETAILS:
WTS screening, overprinting, halftoning for more than five colorants
and the fast halftoning logic need to be able to create gx_color_index
values without using the encode_color routine. This only works if a
device is 'separable'. However, by default, most devices indicate
'unknown'. This change implements a heuristic for checking if a
device is separable. If so then it also determines the various
related parameter values (comp_shift, comp_bits, comp_mask).

Implement 687423 Implement SeparationOrder for psdcmyk device.
DETAILS:
The following changes are for implementing the SeparationOrder
parameter for the psdcmyk device.
The change consists of the following:
1. Several routines which were duplicated in the spotcmyk
and psdcmyk devices were restructured to allow the use of
common subroutines. As part of this effort the various
common DeviceN related parameters were separated into a
substructure (call devn_params). This allows the use of
common routines even though the devices do not have the
same overall device description structure.
2. Changes to the src/gdevpsd.c module for actually collecting
the SeparationOrder parameter data and then using it. Note:
The treatment of separations is different for the process
color model colorants versus the spot colors. The colorants for
the process color model do not have their order changed. The
output file always starts with information for the CMYK channels.
If one of these colorants is not specified in the SeparationOrder,
then the output channel data in the file will simply be 'blank'.
Spot colors follow CMYK data. They are rearranged. Only the
spot colors specified are output.
3. Several checks in src/gdevdflt.c and src/gxcmap.c had to
be removed or modified. These checks were assuming that a
device with a single component uses a gray process color
model and a device with three components used RGB.
A new implementation of shadings, step 49.
DETAILS :
1. gx_default_fill_linear_color_trapezoid wrongly subdivided big areas :
the edge height was not reduced. It could cause an infinite loop.

Fix to make sure that both stroke (CA) and non-stroke (ca) opacity is set.
Support for customer #32 that wants to create transparent effects in PDF
from PostScript input.
DETAILS:
Previously the opacity was set for one or the other (whichever was first)
and only updated when the value changed. Since the 'state' only retained
a single value, the following PS snippet would not set the CA value as it
should to 0.5. Since we never use the 'b/B' fill + stroke painting methods
(our graphics library currently has no device function for this), a PDF
that contains a 'b' method will be decomposed into a 'f' followed by 's'
operation, setting the opacity from the PDF interpreter's retained ca/CA
between the operations.
PostScript snippet to test this:

Fix 687189 for bbox_forward_add_rect infinite recursion.
This problem caused segment faults or apparent hangs with
the x11alpha device. This fix also works for 656414
segfault when using x11alpha
DETAILS:
The problem was due to the bounding box device creating
more and more bounding box devices in the device chain
when the overprint compositor was being used. The x11alpha
device uses the bounding box device. The overprint logic
uses the 'create compositor' logic when a change is made
in the status of the overprint or overprint mode parameters.
However a new compositor is not created each time. Instead
the overprint device simply updates its parameters. The
bounding box device has its own create compositor. This
routine would call its target device's create compositor
routine and then wraps a new bounding box device around the
target's compositor. The combination of many create
compositor calls from the overprint logic and the fact that
the bounding box device adds a new bounding box device
could result in hundreds of bounding devices in the chain.
The fix consists of checking if the bounding box's target
device actually created a new compositor device. Only when
a new compositor was added is a new bounding box also added
to the chain.

Fix for 687402 Missing color on annots.pdf. This is actually
not an error. Instead it is due to some confusion about the
displaying of link annotations.
DETAILS:
To prevent confusion, the following two paragraphs of explanation
were added to the first page of the examples/annots.pdf example file.
"IMPORTANT NOTE ABOUT THIS PAGE: This page was created for the testing
the display of link annotation parameters. The file was created using
Adobe Acrobat 5.0 (and modified using Acrobat 6.0). The displaying of
each annotation is specified in the annotation. By default, Acrobat sets
link annotations so that they are normally displayed by 'viewer'
applications. They are not normally displayed in printed output. That is
the case with these annotations.
Ghostscript checks the display specifications for each annotation. By
default, Ghostscript assumes that the output is 'printed' if the
'OutputFile' parameter is defined. Adding '-dPrinted=false' to the command
line will force Ghostscript to display 'viewer' annotations in all output.
Adding '-dPrinted=true' will disable the displaying of these annotations."

Fix (Type 1 hinter) : Skip empty hint ranges.
DETAILS :
Bug 687393 "Hang with 8.14 from command line".
The test document embeds a font with a hint mask,
which defines a stem range with 'closepath' only.
t1_hinter__skip_stem couldn't handle this case,
because we exclude 'closepath' from the pole list.
We believe that the font is buggy, but provide a tolerance.
EXPECTED DIFFERENCES :
None.
Fix : MSVC6 compiler warnings.
DETAILS :
An "initialized data" warning appeared when MSVC6 performs a release build
with inline optimizations on (The inline optimization inlines small function bodies,
being not marked with the inline keyword).
1. The "uninitialized data" warning in alloc_name_index_is_since_save
in isave.c was a real bug with an indeterministic behavior :
nref.tas.rsize was accessed by names_index_inline from names_string_inline
from alloc_name_is_since_save from alloc_name_index_is_since_save
with no advance initialization.
This bug was not detected because this function is only
invoked when a 'save' unwinds glyph names added to an incremental font,
but doesn't unwind the font - we have no such examples.
IMO existing PS drivers never cvreate such documents.
2. The "uninitialized data" warning in cos_array_add_object appears due to
cos_copy_element_value copies entire 'value' when another variant of an union
has a bigger size and was uninitialized.
The copying of the uninitialized data looks not harmful due to the 'int' type,
but generally it could cause an interrupt on platforms with a tagged memory.
We prefer to suppress the warning with an unuseful initialization,
because the processor time consumption is pretty small and happens not frequently.

EXPECTED DIFFERENCES :

Fix : setcachedevice must not depend on a BuildChar color and on gx_show_text_retry.
DETAILS :
1. The bug 687391 "assert src/gxccman.c:557 again" happened
because BuildChar changed the current color before
setcachedevice calls compute_glyph_raster_params,
and the raster params computed differently than
during the advance glyph raster cache lookup.
2. Removed
if (pgs->in_cachedevice)
return_error(gs_error_undefined);
from gs_setcolor,
because I can't guess it's reason/purpose.
It looks as a rudiment from a pre-repository versions.
3. The assertion also failed with
"-dTextAlphaBits=4 -dLastPage=1 comparefiles\xgfddg.pdf".
In gx_add_cached_char added the case "cc->pair == NULL" :
/* gx_show_text_retry could reset it when bbox_draw
discovered an insufficient FontBBox and enlarged it.
Glyph raster params could change then. */
4. gx_show_text_retry must reset penum->pair due to possible FontBBox change,
see (3).

Fix for 687390 GhostScript 8.11 inserts rendering artifacts
with GIFs as source. The actual problem is an error which
resulted in a pale yellow being shown as a pale pink. This
occurs when dithering on devices which use a 256 color palette.
DETAILS
The halftoning logic assumes that there are the same number
of shades of each color. However the 256 color palette
devices were using a 7x7x5 color cube. I.e. there were 7
shades of red and green, however there were only 5 shades of
blue. The data in the device's color_info (max_color, max_gray,
dither_colors, and dither_grays) indicated that there were
7 shades. The halftoning logic, using this information, was
attempting to display the given pale yellow color by dithering
between 6/7ths and 7/7ths of each component. However the
encode_color routine returned colors which include solid blue
for all cases. This biased the resulting halftoned color
toward blue.
The fix involves changing the 256 color palette devices to
use a 6x6x6 color cube. The same routine pc_8bit_map_rgb_color
is used for all of the 256 color palette devices. Thus the
change consists of modifying this routine and the associated
pc_8bit_map_color_rgb routine. The specification of each of
the devices has to be changed to represent the change in the
cube size.

Fix for incorrect Annotation scaling when an Appearance (/AP) had
scaling that was not unity (1) and the Subtype was not /Stamp.
Fixes Bug #687288 for customer #32.
DETAILS:
The scaling difference in the annotation (object 14 0) was due to
Ghostscript not recognizing the bsiTextStamp annotation Subtype.
Careful reading of the Adobe PDF specification says that if there
is an Appearace stream (/AP dict), then the Form XObject should be
scaled using the method that we perviously only used for /Stamp
Subtype annotations (calcstampscale). The section of the PDF 1.5
Reference Manual is 8.4.4.
The patch is fairly simple, but testing of the regression suite
showed one file, foo.pdf, that was missing the require /Rect entry
in the Annot dict. The patch includes a check and warning for this
problem.
EXPECTED DIFFERENCES:
With this patch, some of the regression files will have slightly
different scaling for some of the annotations, but the differences
are all too small to compare to Adobe. The largest variations are
seen with annots.pdf (our test file) where the scaling ranges from
a low of 0.979191 to a high of 1.01636. The files are:
filename scaling range (was 1)
01_001.PDF 1.0
SyscoCorrugatedprintcard.pdf 1.0 .. 1.00268
annots.pdf 0.979191 .. 1.01636
rf1025.PDF 0.998471
IMO, these are all close enough to be considered progressions.

Fix for 687364 rangecheck in buildshading2 from Quark XPress PS file.
This fix involves the creation of the findcmykcustomcolor and
setcustomcolor functions.
DETAILS:
Ray found that the error message was due to an invalid shading
dictionary being given to shfill. The dictionary has a function
which has a single input and a single output. The numbers are
determined from the sizes of the Domain and Range arrays. Since
the shading dictionary is using a DeviceCMYK color space, Ghostscript
is generating a rangecheck since the function does not have four
outputs.
The file is generating an invalid shading dictionary. Specifically
it generates:

This dictionary has a Separation color space. The given function
is a reasonable function to use with the Separation color space.
As Ray mentioned, it is not correct for a DeviceCMYK color space.
The file is generating a different dictionary for the two interpreters.
In the case of Ghostscript, the dictionary is invalid,
Backtracking through the various procsets inside of the given file
shows that is a mess of function definitions, followed by replacement
of the functions with new definitions. Some of it may be Quarks.
Some of it is labeled:
%%BeginResource: file Jaws_custom_colour_blend_level3_emulation 2.1 0
The results of the search are:
1. Ghostscript does not define 'setcustomcolor' but Adobe Distiller
6.0 does define it.
2. The procsets in the file do provide a definition for
setcustomcolor. Actually the file provides about 16 versions of
setcustomcolor. However the versions provided in the file do
not work.
The PLRM does not mention setcustomcolor. However it is
described in Adobe's "Technical Note #5044 Color Separation
Conventions for PostScript Language Programs". TN 5044 says:
"The following "operators" are not defined in the PostScript
Language Reference Manual, but should be used as pseudo-operators
in your PostScript language output. Separation applications from
Adobe Systems and other vendors will redefine these convention
operators to separate your documents. Your application should
conditionally define procedures with these special names, as shown
later in this document."
The fix to the problem is to provide the functions:
findcmykcustomcolor and setcustomcolor. These are placed at the
end of the lib/gs_lev2.ps. They are placed there because the
implementation requires Separation color spaces which is a level
2 feature.

Fix for a long standing problem that could cause characters to be dropped
when reading a file with the 'read' operator. Bug #687374 for customer #310.
DETAILS:
This was caused by the zread function reading the character (sgetc)
prior to invoking the 'push' macro which could return with
e_stackoverflow (discarding the character). The stackoverflow can
happen more frequently than at MaxOpStack level since the stack
is allocated as blocks, using the e_stackoverflow to signal the
need to add more stack blocks, then retrying the operation.

Fix to implement PDF specification for '/' as a valid name as opposed to
the PS token scanning. Previously //name would be incorrectly scanned as
an immediately evaluated name rather than two names '/' and '/name' which
is correct. Fixes Bug #687277 for customer #440.
DETAILS:
Care is taken to reset the scanner behaviour after a PDF file is finished
and also after an invalid number is scanned. Note that to reset the flag,
the parameter must be set to 'null', not 'false' due to the implementation
in the ztoken.c. Caveat impelementor.
Previously the PDFScanRules was set when an invalid number was found and
was never reset, so this may result is *LOTS* of pdfformaterror messages
for files that have lots of invalid format numbers, but that's what they
get. If this is ever a problem, reseting the PDFScanInvNum can be moved
to pdf_main.ps where PDFScanRules is set to null.
No expected differences.

A new implementation of shadings, step 43.
DETAILS :
1. An optimization :
If an area has a monotonic color,
each subarea has a monotonic color as well,
so the color monotonity doesn't need to recompute.
Doing so because the color monotonity function is not fast
when appied to a ShadingType 1 with a bicubic color interpolation.
2. Bug: is_color_monotonic returned 'true' when the intrval
has zero width by the 1st coordinate.
This is wrong for with ShadingType 1, which uses a 2-argument function.
( The check was a rudiment from a 1 month old implementation of fn_Sd_is_monotonic,
which returned 'false' when the low boundary is at the end of some cell,
and the upper boundary is at the beginning of the next cell.
Actually this case is a zero width interval and the function must return true.

Implementing is_monotonic for cubic interpolation functions.
DETAILS :
The old code ignores extremes of a cubic interpolation function
(except ones at a cell boundary).
It could cause a wrong rendering of shadings with replacing a
randomly big part of the shading near an extremum with a constant color.
The new code fixes that.
The new code caches the interpolation coefficients.
This may cause problems if the function data stream is
modified after the function is build. Likely this must not cause
problems due to gs/lib caches the stream with ReusableStreamDecode.
Also we don't know practical cases.
POLE_CACHE_IGNORE 1 avoids this problem with some slowdown,
(the slowdown exponentially grows with >=3 arguments,
but again we don't know practical examples with >=3 arguments).

Fix for 687337 Zerodivide in cie_cache_mult. Note: There
was a typo in the previous fix.
DETAILS:
The direct cause of the problem, and also the reason that we
have not seen this problem in real world files is that the
050-01.ps test file contains the following color rendering
dictionary.
/RenderDict2
12 dict begin
/BlackPoint [ 0 0 0 ] def
/ColorRenderingType 1 def
/EncodeABC [ {} {} {} ] def
/EncodeLMN [ {} {} {} ] def
/MatrixABC [ 0 0 0 0 0 0 0 0 0 ] def
/MatrixLMN [ 0 0 0 0 0 0 0 0 0 ] def
/RangeABC [ 0 1 0 1 0 1 ] def
/RangeLMN [ 0 1 0 1 0 1 ] def
/RangePQR [ 0 1 0 1 0 1 ] def
/TransformPQR [ {} {} {} ] def
/WhitePoint [ 1 1 1 ] def
Note: The matrices full of zeroes do not represent real
world data. The zero matrices will result in all output
component values being zero no matter what the inputs.
Using this data, Ghostscript uses the given ranges and
matrices to calculate values for DomainABC and DomainLMN.
The results are [0, 0] for each domain. The domain values
are later used to calculate a scaling factors which is
also 0. Calculations, which use one of these values as
a divisor, then generate a divide by zero exception.
One option to fix this problem would be to check for zero
before doing any calculations with the scaling factors.
However another and simpler option is to check for the zero
factors when they are crated and set the value to a value
which will not cause the divide problem. Note: Even though
we are using a dummy factor (1.0), the zero matrices still
result in zero output values from the calculations.

MSVC compiler: allowing Precompiled Headers, Incremental Compilation, Edit & Continue.
DETAILS :
These options are applied to debug build only.
They dramatically improve the development technology.
Automated Precompiled Header speeds up the compilation slightly.
For best results should reorganize gs header files.
Incremental Compilation speeds up the rebuilding after editing source code.
Edit&Continue is a powerful tool for debugging. Together with incremental compilation
it allows to regenerate the object code during a debug session,
and continue the debugging with the new code without restarting the program.
Press F10 after you changes source code and enjoy.
F7 resets the session - forget it.
Another related tool is the "Set instruction pointer" debugger command,
which is available only from Tools/Customize/Commands/Debug.
It looks as an yellow arrow with a blue thin curved arrow.
Move it to your toolbar and enjoy.

DETAILS :
Working on bug 687351 with CAIB_highres_page4.pdf, we detected a set of old bugs.
They caused a heap corruption and crash.
To reproduce the crash apply the patch of the bug 687351 to lib/pdf_font.ps
(that patch will be committed AFTER this one).
1. pdf_resize_resource_arrays was called with a wrong array size (gdevpdtc.c).
2. pdf_resize_resource_arrays did not expand CIDToGIDMap (gdevpdtf.c).
3. gs_type42_glyph_info accepted a wrong type of the return value of get_glyph_index.
4. Copying a CIDFontType 2, CIDCount was wrong (gxfcopy.c).
5. pdf_obtain_cidfont_resource wrongly processed the case of shared font descendents :
font compatibility was not checked, rather they may have different Metrics,
Metrics2, CDevProc, CIDMap (gdevpdtt.c).
6. Implemented a dynamic expansion of CIDMap for copied fonts.
7. In font copies CIDMap used the code 0xFFFF for representing unmapped glyphs.
8. Inserted the comment into gdevpdtf.c :
/* fixme : Likely pdfont->u.cidfont.CIDToGIDMap duplicates
pdfont->FontDescriptor->base_font->copied->client_data->CIDMap.
Only difference is 0xFFFF designates unmapped CIDs.

Add support for 16 bit deep images that is part of PDF 1.5.

Implementing current point with double precision.
DETAILS :
The old code stores the current point in pgs->ppath->position
with the 'fixed' representation in the device space coordinates.
This appears insufficiently precise if a document constructs a path
with multiple 'rlineto' or 'rcurveto'. A significant to error accumulation happens.
We implement the current point with 'double', duplicating pgs->ppath->position
with the new field gs_imager_state::current_point.
We can't replace pgs->ppath->position with the new one due to several reasons :
- Sometimes (in the text processing, in arc processing and in reversepath)
a new current point is computed when imager state is not accessible.
- Don't want to spend processor time for conversion double to fixed,
whenever a fixed is needed.
- Don't want to modify many of low level modules;
Text operation always round the current point to 'fixed'.
Note that the convertion from fixed to double is always precise,
therefore we widely use it with text operations.
Thus this improves the precision of moveto, lineto, curveto,
rmoveto, rlineto, rcurveto, but the precision of other operators
left as it was. Likely there is no strong need to improve text operations
due to pixel rounding, but it would be useful to improve arc, arcn, arct, arcto.
However an improvement of arc operations isn't a high priority,
and after this patch becomes a local change.
We removed ppath->outside_position, because
pgs->current_point now effectively handles this feature.
Due to that the rounded pgs->current_point may be unequal to pgs->ppath->position
when the current point is outside the range.
The configuration flag PRECISE_CURRENTPOINT defined in gxstate.h
helps to debug the new code with raster comparizon with the old code.
PRECISE_CURRENTPOINT 0 works same as the old code except the
coordinate clamping. Therefore once tested with the comparison,
the further validation reduced to a validation of the code
swtched by the flag - this part pof code is pretty small.
The mode (PRECISE_CURRENTPOINT 0) **MUST**NOT** go to production
due to the dropped clamping. PRECISE_CURRENTPOINT 1 handles the clamping.

Log message:
Implement 687347: Implementation of the PDF encryption feature:
EncryptMetadata. Past versions of the PDF encryption have always
encrypted metadata. With this feature it is possible to NOT encrypt
metadata streams. I.e. By adding '/EncryptMetadata false' to the
encryption dictionary.
DETAILS:
There are two pieces to the implementation:
1. The calculation of the user password key includes an additional
step of feeding 0xffffffff to the md5 input if EncryptMetadata is
false. (Ask Adobe, not me.) The PDF 1.5 spec. says that
EncryptMetadata is an undocumented feature of PDF 1.4. This
implies that this action needs to be done for values of R in the
Encrypt dictionary of 3 or higher. However testing with Acrobat
5.0 and Acrobat 6.0 shows that this is not done for R = 3. Thus
we check for R >= 4.
2. Testing with Acrobat 5.0 and 6.0 has verified that the encryption
of metadata streams is controlled by EncryptMetadata in both versions.
Thus we check for PDF 1.4 and higher (R >= 3) and if so then we check
the stream type and the EncryptMetadata flag to determine if a stream
needs to be decrypted.

Add a simple C program that uses the jasper library to parse JPX (jpeg2k) image files and embed
them in a PDF 1.5 document. Useful for testing as there are few producers available at the moment.
DETAILS:
We make no attempt to parse the required metadata (resolution and so on) ourselves. It would be
simple to add this so that the program can stand alone. On the other hand, jasper is capable of
opening a number of other image formats and encoding them to jpx streams. We don't do that either,
but it would also be easy to add support for so that JPXDecode versions of arbitrary images could
be embedded.
Because of this, it's possible to embed e.g. baseline jpeg data instead of a jpx stream if you
feed the program the wrong file. Caveat executor.
Based on the jpegtopdf program by Tor Andersson.

DETAILS :
This change is algorithmically equivalent.
1. Removed the old code BAND_INDEPENDENT 0.
2. Simplified fill_slant_adjust with removing low useful variables.

Fix : Raster depended on bands, step 3.
DETAILS :
Bug 687222 "Raster depends on bands".
Switching to the new code.
Now trapezoid sides are independent on bands, clipping and scans.
Any trapesoid side is equal to some flattened piece of an outline segment.
A massive difference happens due to the old code recognized low trapezoids as rectangles.
The new code does not because it checks the verticality with longer bars.
EXPECTED DIFFERENCES :
Almost all comparefiles render differently.,
but mist differences are single pixels.
A dozen of files give dual pixel differences.

Implementation of 687326 Enhancement: Handling of PDF 1.5encryption.
DETAILS:
The PDF 1.5 specification has added several some features for
encryption of PDF documents.
1. The new encryption changes are indicated by a /R value of
4 in the Encryption dictionary. Note: The encryption algorithm
is the same as /R = 3.
2. The encryption handling for strings and streams may now be
specified independently. Current possibilities are 'Identity'
and the standard handler.
Note: There are more encryption features in the PDF 1.5 specification.
HowevertThe only means that I have for generating test files for these
new encryption features is Acrobat 6.0. This patch will decode files
which are encrypted using Acrobat 6.0. There is one more feature
(EncryptMetaData) which will be the subject of a separate patch.
Between the features covered by the current patch and the EncryptMetaData
patch, this includes all of the capabilities that are available to a user
of Acrobat 6.0. Since Acrobat 6.0 is the major producer of files with
these new encryption features, Ghostscript will have the ability to
decrypt files which we are likely to see in the near future.

Fix for 687274 White areas appear shaded.
DETAILS:
This 'problem' is caused by a 'feature'. The high resolution transfer
function deliberately has a piece of logic that forces any shade of gray
that is not pure white (i.e. greater than 0.998) to halftone with at
least one pixel being set in the output. This keeps nearly white shades
from being washed out.
We have seen several instances in which this 'feature' causes a problem.
The fax output format tiffg4 has been bitten by this problem since it is
commonly used at 204 dpi.
This change removes this feature.

Fix (pdfwrite) : Errors were missed processing a shading data stream.
DETAILS :
Bug 687307 "A ShadingType 7 differs from Adobe."
shade_next_flag interpreted a wrong data as End-Of-Data,
so that some wrong documents were passed with no error.
Now pdfwrite handles the bad shading data exception separately from
other errors: the shading is fully written and the error is signaled
to the PS interpreter after that. Note that other errors terminate immediately
with inconsistent data written to the PDF output. We did the special
processing to provide a better conformity to some buggy Genoa tests,
which paint a shading with a wrong data in a stopped context.
Besides that, we cancelled the default implementation fallback
when pdf_setfillcolor fails. The old implementation caused
shadings to convert into a huge set of rectangles written to PDF.
We believe that signalling an error is the right reaction for this case.
EXPECTED DIFFERENCES :
pdfwrite :
446-01.ps now prints error message to the raster. This is a progression.
483-05.ps now prints error message to stdout. This is a progression.

A new implementation of shadings, step 36.
DETAILS :
Implemented lazy wedges : do not create a wedge,
if both neighbours of a line were divided at same point.
It reduces the number of constant color triangles to fill.
Since this algorithm consumes an exponential RAM of the wedge nesting,
we restrict the wedge nesting with 9. For doing that we enforce
subdivision of large patches into chunks with <=512 pixels length sides
- see LAZY_WEDGES_MAX_LEVEL.

A new implementation of shadings, step 34.
DETAILS :
Improving the ShadingType 1 with applying the generic algorithm.
The generic algorithm is extended for 2-argument functions.
Also fixing the configuration switch DIVIDE_BY_PARALLELS,
which was unintentionally set to 1 by the previous patch.

Fix : A bug in fn_Sd_is_monotonic.
DETAILS :
Monotonic intervals were computed wrongly due to
a wrong cell boundary condition. With no Encode
it overestimated the number of cells in 1.
This patch also extends fn_Sd_is_monotonic for multi-argument functions.
Actually it checks whether both points are within same cell.
This is fine with linear functions,
but for 3d order we would like to check for zero derivatives
within the interval specified by 2 vectors.

A new implementation of shadings, step 33.
DETAILS :
Improves the performance of radial shadings :
For a faster painting, we apply fill adjustment to outer annula only.
Inner annula are painted with no fill adjustment.
It can't cause a dropout, because the outer side of an annulus
gets same flattening as the inner side of the neighbour outer annulus.
For other shadings this chande is algorithmically equivalent.
EXPECTED DIFFERENCES :
A minor difference with axial shadings :

Fixes bug 687317.
Fix pdfwrite allowable Permissions for EncryptionR=2.
Fix default Permissions.
DETAILS:
The code was assuming that the extra permissions should be 0's,
when in fact they should be 1's. The fixed code is a bit more
conservative and requires that all reserved bits match the PDF
specification. Set the default permissions to -4 which allows
everything.

A new implementation of shadings, step 32.
DETAILS :
1. Implemented axial shading with a Coons patch.
It gives more regularity with area decomposition and trapping.
2. Optimized tensor shadings for the case when the gradient is
parallel to the quadrangle sides.
Note that the old code applies 1/2 pixels fill adjustment when
painting stripes of the shading, generating overlapped stripes.
Instead that the new code generates non-overlapping stripes,
and applies a trapping emulation at the shading boundaries with 1/8 pixels.

Add a parameter which prevents the non-standard four element PageSize
entry in the InputAttributes from being included. This prevents problems
with PostScript programs that examine the InputAttributes entries in an
attempt to pick the 'best fit' rather than relying on the setpagedevice
logic. Also most 'real' printer devices don't support arbitrary page
sizes, so automatic rotation is defeated if the range type page size
in included. The option is -dNORANGEPAGESIZE. Bug #629335.

Add the path to the code directory (gsconf.codedir) for invocation of the
update_baseline/update_pdfbaseline.
Initial implementation of the JPXDecode filter using the JasPer library
for decoding the JPEG 2000 data. This version only implements a
postscript-level filter; PDF support will follow in another commit.
DETAILS:
A new FEATURE_DEV, 'jpx.dev', is added to the makefile to enable
support. The jasper library must be available to link with in this case.
The library is autodetected in the autoconf build, but not yet enabled
on other platforms.
The implementation leaves a little to be desired. While JasPer is
robust, it provides no way to connect its internal stream architecture
to ours, so we end up buffering all the data. This seems to be the best
we can do without modifying the library.
We try to handle data from a number of colorspaces, but the spec is a
little vague on what is required. We convert YUV to RGB internally, but
do not handle sub-sampled planes.

Improving the filling algorithm, step D7.
DETAILS :
When filling an individual trapezoid, a shortcut
for parallelograms could miss some pixels.
When the left boundary rounds to a vertical line
and the right one does not, for the right boundary it
wrongly applied same zero sampling as for the left one,
in spite of the right boundary can cross pixel centers.
We realize that the shortcut could improve a view
of some parallelograms. But in same time we detected that
in alphabet.ps with 72dpi a parallelogram was replaced
with a wider one, causing a worse view of the character '#'.
So its usefullness is arguable.
Both features can't provide simultaneousely
due to the device interface can't pass a flag whether
an exact coverage is required.
Therefore we drop the shortcut.

A new implementation of shadings, step 7.
DETAILS :
Documenting the current state of the development,
because we need to delay the project.
EXPECTED DIFFERENCES :
None.
[src/gxshade6.c]

Adapt makefile support for compiling in zlib to support v1.2.x rather
than 1.1.x. Linking to a shared version is unaffected.
DETAILS:
The zlib source was re-arranged from the 1.1.4 to the 1.2.x releases.
While binary compatibility was maintained, and we link just fine to a
separately build dynamic zlib, our custom makefile support for compiling
in the library source no longer works.
Rather than add a 'ZLIB_VERSION' makefile variable and the attendent
configuration costs, we've simply migrated completely to the new (much
faster) 1.2.x series. 1.2.1 is now the minimum version to be used if you
wish to compile zlib as part of Ghostscript.
Improving the filling algorithm, step D5.
DETAILS :
It's a preparation for fixing a problem while filling a single trapezoid.
This change improved a debug drawing.
EXPECTED DIFFERENCES :
None.

2004-02-16T09:13:12.000000Z Igor Melichev
A new implementation of shadings, step 6.
DETAILS :
The new code is disabled with NEW_TENSOR_SHADING 0.
1. Implemented a debug drawer draw_wedge.
2. dbg_nofill was not properly initialized.
3. Removed a debuging hack.
4. removed unused variables.
EXPECTED DIFFERENCES :
None.

This change is algorithmicaly equivalent.
EXPECTED DIFFERENCES :
None.

2004-02-16T08:21:15.000000Z Igor Melichev
Improving the filling algorithm, step D2.
DETAILS :
It's a preparation for fixing a problem while filling a single trapezoid.
This change is algorithmicaly equivalent.
It branches out the rectangle case and simplifies it.
Some macros are moved by necessity.
EXPECTED DIFFERENCES :
None.

Fix for 687294 psdcmyk device does not write resolution correctly to PSD
files. This change adds a 'ResolutionInfo structure' into the 'Image
Resources' section of the output file. This structure specifies the
horizontal and vertical resolution of the image. (Note: Adobe's support
of asymetric resolutions is poor.)
[src/gdevpsd.c]
2004-02-15T14:51:21.000000Z Igor Melichev
Fix: Improving the documentation (comments) about the filling algorithm, improved.
DETAILS :
The prevoius change to the comment appears wrong,
i.e. the old expression "x + xf/h + 1"
appears correct due to compute_ldx subtracts h from
the remainder but doesn't add 1 to the integer part,
which is x.
EXPECTED DIFFERENCES :
None.
[src/gdevddrw.c]
2004-02-15T11:31:10.000000Z Igor Melichev
A new implementation of shadings, step 5.
DETAILS :
The new code is disabled with NEW_TENSOR_SHADING 0.
It fixes some dropouts.
1. Improved the documentation (comments).
2. Improved the debug painting with NEW_TENSOR_SHADING_DEBUG.
3. Fixed bugs in the linear equation solver.
4. Improved the wedge generation.
5. Reduced the usage of transpozed coordinates.
EXPECTED DIFFERENCES :
None.
[src/gxshade6.c]
2004-02-15T11:28:34.000000Z Igor Melichev
Fix: Improving the documentation (comments) about the filling algorithm.
DETAILS :
We believe that the comment about "x, xf" was wrong.
Note tha the old expression was "x + xf/h + 1",
and we changed it to "x + xf/h". We believe that
the new one corresponds to the code.
EXPECTED DIFFERENCES :
None.

EXPECTED DIFFERENCES :
None.
[src/gdevpdfo.c]
2004-02-13T08:08:35.000000Z Igor Melichev
pdfwrite : NoEncrypt option by a special customer request.
DETAILS :
The implementation isn't fool proof : an inaccurate specification
may generate an inconforming document.
The specified key is not encrypted in any dictionary.
The specification must use an external representation :
a name to be prepended with slash, a string to be bracketed, and so on.
EXPECTED DIFFERENCES :
None.
Improving the filling algorithm, step D1.
DETAILS :
1. The 'peak' condition was too weak.
Caused minor differences in rasters with dropout prevention.
2. Expanded loop_fill_trap_np in the inner trapezoid loop.
This change is algorithmically equivalent.
3. Cleaned the inner loop with moving out the computations if ybot, ytop.
This change is algorithmically equivalent.
4. Moved the (ybot < ytop) check outside the trapezoid loop.
This change is algorithmically equivalent.
5. Inserted 'const' into loop_fill_trap_np.
6. Inserted the section "Reserved to improve the banding"
to simplify experiments with it.

Fix (pdfwrite) : Charproc can change scale before calling setcachedevice.
DETAILS :
Bug 687290 "pdfwrite generate too large glyphs".
To know that CTM changed by a charproc before setcachedevice or setcharwidth,
we set identity CTM before entering the charproc.
If setcachedevice or setcharwidth decides to fall back to
the default implementation, we restore the CTM in there.
The condition in gdevpdtt.c 1931 is changed,
causing minor differences with Bug687044.ps and muur.eps .
We found that a further improvement would be useful for
a better handling of a composite font with a Type 3 descendent.
Opened the new bug 687298 about this issue.
Differences with Bug687044.ps and muur.eps may be related to it.

Update our copy of the ijs source to the latest cvs source, which
includes libtool support for building a shared library version. Closes
bug 687278.
Fix: Improving the decision whether the dropout prevention to be applied.
DETAILS :
1. The old code applied the dropout prevention
if gx_fill_params::adjust = 0.
It worked since the latter was set to 0 only for characters.
Now we intend to discontinue the fill adjustment with shadings,
so the old condition won't be applicable in further revisions.
Therefore we reserve the value -1 of gx_fill_params::adjust
especially for designating characters with a dropout prevention,
and percept it in the filling algorithm (We tried to use
new special flag for designeting characters,
but it requires an enhancement to the clist language.).
2. The old code has a problem with PaintType 2 fonts :
it applied the dropout prevention to strokes.
This patch fixes that with checking PaintType in gxtype1.c .
EXPECTED DIFFERENCES :
A progression with CAT_LOGO.ps due to (2).

Simplifying the filling algorithm, step C19.
DETAILS :
This is an optimization of the trapezoid algorithm :
1. gx_fill_trapezoid_narrow derives a specialization from
fill_loop_by_trapezoids__pr.
2. Simplified the GX_FILL_TRAPEZOID template with moving the
fill_direct check outside the template.
3. Renamed gx_default_fill_trapezoid_as, gx_default_fill_trapezoid_ns,
gx_fill_trapezoid_narrow.
EXPECTED DIFFERENCES :
None.
Simplifying the filling algorithm, step C18.
DETAILS :
This is an optimization of the new scanline algorithm.
merge_ranges doesnt need to enumerate flattened pieces of monotonic curves.
Minor change : renamed "monotonic" into "monotonic_y".
EXPECTED DIFFERENCES :
None.
Simplifying the filling algorithm, step C16.
DETAILS :
Switching to the new scanline algorithm based on the flattened iterator.
Now both the trapezoid and the scanline algorithm use same flattened path.
Differences in rasters appears due to 2 reasons :
1. An inprecise expressions used in the old algorithm in gx_curve_x_at_y :
the iteration of midpoint_fast accumulates a big rounding error.
The new algorithm have smaller error due to 3*log2(N) fraction bits
while the coordinate accumulation, where N is the number of flattened segments.
2. The old algorithm used inprecise expressions in pco_monotonize.
The new algorithm applies a flattening instead the monotonization.

Simplifying the filling algorithm, step C7.
DETAILS :
This is a preparation for removing the coord_near filter
from the flattening algorithm.
We believe that the the coord_near filter was implemented for
two purposes : (1) prevent the filling algorithm from
zero-height segments, and (2) speed up the filling with
reducing the number of vertices in the polygon.
Now the filling algorithms can handle zero length segments
due to conformity to gx_flattened_iterator.
Thus the reason (1) is not longer important.
The skipping of some vertices speeds up in 3% at 600dpi
rendering with ppmraw to null file.
But sometimes it produces raster distortions,
such as an asymmetric raster for symmetric outlines.
When we fixed the distortions,
the speeding up appears within 0.5%.
We decided to remove the coord_near filter, because so small
echonony of processor time is less important than the distortions.
This patch introduces a new swicth DONT_FILTER_SMALL_SEGMENTS,
and make the compilation of coord_near filter to depend on it.
EXPECTED DIFFERENCES :
None.
pdfwrite : Implementing the PDF 1.4 encryption, step 14.
DETAILS :
Elements of pdfmark elements were not encryptrd.
Since gs/lib/gs_pdfwr.ps serializes pdfmark elements,
we would like to encrypt them before the serialization.
However it would require to implement a new PS operator to pass the
encription keys from the device to the PDF interpreter.
Since this way appears cumbersome, we decided to
unserialize data in the device. For doing that we implement
a simple parser in pdf_put_composite.

Fix : Partially restoring the old behavior of the filling algorithm.
DETAILS :
When we dropped the compatibility with the patch
http://www.ghostscript.com/pipermail/gs-cvs/2004-January/004061.html,
one case of the flattening condition was not perfect.
Sorry for detecting this late.
Now we put another condition, which differs from both the old and the last one,
but the new one is symmetric and provides lesser distortions.
EXPECTED DIFFERENCES :
This change causes a massive difference,
which may partially undo the difference of the patch mentioned above.

Simplifying the filling algorithm, step C4.
DETAILS :
In the enabled code this change is algorithmically equivalent.
In the disabled code it provides a variable threshold
for the 'coord_near' predicate.
Doing so because the old scanline algorithm uses a zero threshold.

Fix for Bug 687255 pcl output shifted to bottom of page. Correct
the order of the PCL commands at the start of page for the ljet devices.
DETAILS:
This problem surfaced when a previous fix 686815 was made. That fix
corrected a line of code which was setting the page seize in the output
file.
With the correct page size being specified in the output file, there were
some side effects. Setting the page size resets several other items,
including the starting page X and Y offsets.
The fix for this problem consists of simply moving the setting of the page
size three lines earlier in the file. Now the page size is set prior to
the page X and Y offsets, which are set as part of this line:
fputs(page_init, prn_stream);

1. Removed the 'filtered2' subclass of gx_flattened_iterator;
2. Renamed the 'filtered1' subclass to 'filtered'.
3. Removed CURVED_TRAPEZOID_FILL_HEAVY_TEST.
4. Removed the CURVED_TRAPEZOID_FILL0_COMPATIBLE 0 section from
gx_flattened_iterator__prev_filtered because it
can't provide the backscan consistency.
5. Made other configuration flags to be local for gxpflat.c .
EXPECTED DIFFERENCES :
None.
Add check for missing raster image before getting the date of the raster.
If raster is missing, run update_***baseline script to generate it since
the file must be new since the last regression run. Bug 687245.
Removed the obsolete configuration switches NEW_TT_INTERPRETER and TT_GRID_FITTING.
DETAILS :
It doesn't change the algorithm.
EXPECTED DIFFERENCES :
None.
Fix (the new TT interpreter) : st_gs_text_enum_max_ptrs was wrong.
DETAILS :
This doesn't change the algorithm because this constant is never used.

Simplifying the filling algorithm, step B3.
DETAILS :
1. Removed the disabled code MERGE_COLLINEAR_SEGMENTS 0
2. Removed the disabled code CURVED_TRAPEZOID_FILL 0
3. Removed the dependence on TT_GRID_FITTING from gxfill.c .
EXPECTED DIFFERENCES :
None.
Simplifying the filling algorithm, step B1.
DETAILS :
This starts a new sequence of patches to the filling algorithm.
It's goal is a further simplification.
We deetected that MERGE_COLLINEAR_SEGMENTS 1 section is an old optimization,
which speeds up in 1.3% and complicates the code in 30%.
Besides that, it causes inprecise results with the dropout prevention.
At last, the name "MERGE_COLLINEAR_SEGMENTS" doesn't reflect
its effect : actually it merges segments nearly parallwel to coordinate axis,
which may be unlimitedly long and have an unlimited angle.
Therefore we believe that this optimization is not well defined,
appears unuseful, and to be cancelled.
This patch is a preparation for removing the MERGE_COLLINEAR_SEGMENTS
section. We made this switch global and we bracketed more code sections,
which appear unuseful without MERGE_COLLINEAR_SEGMENTS.
This patch almost is a change to a disabled code.
But the change to gxfill.c ln 1238,1241 goes to the enabled code
and appears algorithmically equivalent :
with MERGE_COLLINEAR_SEGMENTS 1 this branch is equivalent to noop.
EXPECTED DIFFERENCES :
None.

DETAILS :
Bug 687266 "Accurate curves may be inaccurate.".
EXPECTED DIFFERENCES :
None, because normally PS doesn't use "true .setaccuratecurves".
Testing with "true .setaccuratecurves", got no difference with -r72.
Thus our testbase doesn't contain interesting curves.

Create a new dynamic header 'gconfigd.h' for non-platform-specific defines. Variables like
GS_LIB_DEFAULT which were previously tacked onto the end of gconfig.h have been moved to the new
header. This change is necessary to pass the default path for the persistent cache from the
makefile.
DETAILS:
The persistent cache is implemented in the gp layer, but previously it was illegal to access
gconfig.h from code inside the graphics library, it the sense that the build would fail. This is
because of the crazy way operator definitions are collected in dev files before they are
consolidated in gconfig.h.
We don't want to use gconfigv.h because that header is platform-specific is generated by different
code on every platform. Therefore, while this isn't a real fix for gconfig.h circular inclusion
issue, a new header is reasonably motivated.
Fix : Don't apply pco_accurate when filling a path.
DETAILS :
When a path is is being stroked, it first converts to the stroke
outline, and pco_accurate is being applied. When the stroke outline
is being filled, pco_accurate was applied at second time with no
useful reason. When it fills a character, pco_accurate disturbs the
hinted outline. Thus it must not apply with 'fill' in any case.
EXPECTED DIFFERENCES :
None, because normally PS doesn't use "true .setaccuratecurves".
Testing with "true .setaccuratecurves", almost all tests

Fix : The PCL interpreter doesn't provide pattern streams (continued).
DETAILS :
1. Restored the PATTERN_STREAM_ACCUMULATION 0 code from gdevpdfv.c revision 1.27.
It provides a conversion of a pattern tile into a PDF pattern object.
2. Passed have_pattern_streams to corresponding parts of pdfwrite.
3. Added a check for have_pattern_streams into zpcolor.c .
It is useful for debugging PS interpreter
with passing have_pattern_streams=false to gs_state_set_client.
With PS interpreter the new code never executes (unless one changes
the call to gs_state_set_client).

Fix (PDF interpreter) : CropBox computed wrongly.
DETAILS :
Bug 687244 "wrong interpretation of negative mediabox coordinates".
The bug title appears incorrect. Actually the problem is caused by
negative CropBox coordinates.
.pdfshowpage_Install translates the coordinate system
to provide positive coordinates, but pdfshowpage_finish did not
account the translation when writing the CropBox.
Therefore it the resulting CropBox was inconsistent with the painting
when the source CropBox uses negative coordinates.

The patch
http://www.ghostscript.com/pipermail/gs-cvs/2004-January/003988.html
appears incomplete, because it works only with

The problem happens due to Decode arrays considered always unequal.
This patch :

Fix : The PCL interpreter doesn't provide pattern streams.
DETAILS :
gx_pattern_cache_lookup falied when called by the PCL interpreter
because the PCL interpreter doesn't provide high level pattern streams.
Actially the compatibility of the graphics library to the PCL interpreter
was broken since gsptype1.c revision 1.16.
This patch introdices a new argument for the function gs_state_set_client.
Using the argument, a client tells to the graphics library
whether the client provides pattern streams. If not,
the graphics librery emulates the old behavior based
on raster parretns only.
The new flag gs_imager_state::have_pattern_streams stores the
compatibility mode. We would prefer it to be a member of the
graphics library instance, but the instance is not implemented yet.
Storing it to gs_imager_state may cause some undeserable effects,
especially when a device creates a temporary graphic state for
an internal use (the clist device is an example).
We assume that none of devices provides pattern streams,
and this assumption should be reasonable for current applications.
The mechanizm for generating patters streams is still
coded specifically to the PS interpreter in pattern_paint_prepare
in zpcolor.c . This solution to be considered as a temporary one.
We should refactor it into 2 parts : one specific for the PS interpreter,
and another one being common for all applications,
which should be a part of the graphics library.
This patch had passed the regression test with the PS interpreter,
but it was not tested with the PCL interpreter.
Debugging it with PCL to be a next step.
EXPECTED DIFFERENCES :
None.
Fix for "687252 subfiledecode errors on includes greater than the
size of a uint". In spite of the bug name, the problem is not
related to the actual size of the subfile or to the size of a uint.
The actual problem is a missing required parameter: EODCount.
However Adobe once again ignores the missing parameter and what is
specified in the PRLM-3rd.
DETAILS:
The given test file has a SubFileDecode filter without the required
EODCount parameter.
Ghostscript is rejecting the test file because the parameter is not
defined. The RangeCheck error message is the result of the following
piece of code in zfilter.c:
if ((code = dict_int_param(op, "EODCount", 0, max_int, -1, &count)) < 0)
return code;
This sets a default value of -1 for EODCount and then checks it
against the range 0 to max_int. Thus when EODCount is not found
we get the rangecheck since -1 is outside the allowed range.
In spite of the fact that the EODCount is a required parameter,
Adobe Distiller 6.0, my CP1700PS printer, and CPSI 3010.105 print
this file without complaint.
This fix changes the default value to 0 to match Adobe and adds a
comment explaining why the code differs from the spec.

Fix (type 1 hinter) : Wrong outline with a huge scale.
DETAILS :
An arithmetic error happened when scaling a glyph to a huge size
(about 100000 pixels), causing a wrong outline.
Actually some coordinate values were replaced with zeros.
Thanks to Jeong Kim for detecting that.
The bug was detected with -r1500 with the test file of
the bug 686975 "Black box when converting to tiff".
Note that the bug report is wrong :
it says that the document with -r150 is bad and -r1500 is good.
Comparing rasters with Adobe we concluded exactly vise versa :
-r150 was compatible and -r1500 was incompatible.
After this patch both resolutions are compatible to Adobe.
Probably the user won't like them due to a bug in the document :
it paints a huge glyph, which is a hundred times bigger than the page size.
The document needs a fix.

Fix for 687247 x11 device fails with CMYK on 8bit display.
DETAILS:
Inside gxcmap.c, the handling of color mapping for most devices is either
halftoned or direct. However the x11 device when in 8 bit mode, and
possibly other 256 color devices, use a slightly different path. First
the color is processed in direct mode. If a color is not in the palatte
and halftoning is required, then gx_no_color_index is returned as a
color value. Then the color is processed as being halftoned. However
this last path was dropped from CMYK colors with revision 8.0.

Initial commit of the persistent cache implementation. This version supports only the *nix
platform and does not include any eviction logic. Also currently the cache directory and
empty 'gs_cache' index file must be created manually.
DETAILS:
Two new calls have been added to the gp layer: gp_cache_insert() and gp_cache_query(). These
take a byte buffer as a key under which another buffer can be stored or recalled. In addition to
the key, buffers are filed by 'type' which provides a separate namespace for each kind of
data. These types should be one of the GP_CACHE_TYPE_* defines in gp.h.
The query call takes a callback for allocating the buffer to be filled. Thus, all memory
management for the key and value buffers is handled by the client and the query returns
the data (if any) within a single call.
A pair of postscript test operators, .pcacheinsert and .pcachequery are provided in zmisc.c,
however they are disabled by default to prevent access to the cache by malicious postscript
programs. They operate only with the 'test' type, so a denial-of-service attack is the only
real risk; however we anticipate all access will be from C code. Compile with the DEBUG_CACHE
preprocessor symbol to enable these.
Improvements and implementations for other platforms are to follow.

Fix problems with the "image" device when the palette is an 8-bit gray
palette (uses the image8 device with num_components == 1). Since the
DeviceN changes, changing num_components requires also setting the
gray_index value appropriately. Also the rgb to color mapping function
did not allow for num_components == 1 and used uninitialized values for
the green and blue comonents. Fixes bugs 458261, 686909 and 687204.
DETAILS:
The gray_index value was being left at GX_CINFO_COMP_NO_INDEX, so the
gx_device_has_color macro indicated a color device. This means that
when the gs_initialize_wordimagedevice function changed the num_components
value to 1, the gray_index was incorrect (should be 0 for a gray shade
device).
Also the mem_mapped_map_rgb_color function didn't check for num_components
== 1, thus using uninitialized cv[1] and cv[2] values and getting incorrect
palette selections. Also I optimized the single component case a bit as
well as an "early out" for both color and monochrome when diff == 0 (can't
get any better than a perfect match).
I guess 8-bit monochrome image devices haven't been used much.
Expected Differences:
none. (we don't test ps2epsi in the regression suite).

pdfwrite : Merge redundant images.
DETAILS :
Bug 687224 "large pdf file size".
With this change pdfwrite compares images for equality
and merges same images into a single XObject, except for inline images.
A new pdfwrite device parameter MaxInlineImageSize controls
inline images. See gs\doc\Ps2pdf.htm . Use it to disable
inline images if the source document contains multiple redundant
small images.
A new vitrtual function cos_object_t::cos_procs->equal is implemented
for object comparizon. But the current implementation is restricted
with current needs. Particularly it doesn't implement cos arrays,
and assumes equal stream segmentation for equal streams.
To be improved someday.
Note that an image is copied to temporary file before a comparizon.
If the image appears redundant, the current implementation sometimes doesn't
release the space consumed in the temporary file. Therefore the disk must
have enough space for storing all copies. We could improve this using
a smarter method than cos_stream_release_pieces, because an image can interlive
only with same image of an alternative compression.
To be improved someday.

Unequivocally include stdlib.h in echogs.c to avoid a warning on the Sun ONE Studio 7 compiler as
reported in bug 687234.
DETAILS:
The code in echogs.c calls exit() which is defined in stdlib.h. However it was not including that
header (except) on VMS because of portability concerns, resulting in the reported 'implicit
function definition' warning. The echogs program must be available before genarch runs and the
std.h-based portability headers are available, so wide build support for this code is important.
However, such platforms are now very old and comments elsewhere in the code suggest that any
compiler supporting ANSI prototypes as we now require will also have a stdlib.h that defines
exit(). If this change causes a problem, #ifdef code similar to what was used in gp_unix.c can be
used instead.

Implementing a True Type grid fitting, step 10.
DETAILS :
This patch changes a disabled code only.
It fixes minor problems with hint generation :
1. Implemented an "overall" hint, which
designates an outer side of a glyph,
being nearly parallel to a coordinate axis.
It aligns a stem end rather than stem sides, and
simulates top/bottom alignment zones.
This branch appears low useful and was not enabled.
Maybe will remove it later.
2. Change to gxhintn.c is algorithmically equivalent.
3. The default value of GritFitTT is changed to 2,
because we can't to provide a compatibility
of the autohinted glyph size to the TT interpreter.
4. Improved hint_by_tangent : some slower but a better choice.
EXPECTED DIFFERENCES :
None.
Transliterate '\0' character in PDF names to "BnZr" instead of
'?' to reduce the chance of name collision.
DETAILS:
TeX generates Type 3 fonts with single character glyph names equal to the
character codes, i.e. /Encoding [(\000) cvn (\001) cvn ... /? ...] . PDF
writer used to transliterate '\0' to '?' because #00 escape is invalid.
This conflicts with /? glyph name, which also occurs in the same font.

Implementing a True Type grid fitting, step 8.
DETAILS :
1. Renamed monotonize_internal to gx_curve_monotonize.
2. Allowed the curved trapezoid algorithm for non-characters.
2 fragments changed for this purpose : passed all_bands to intersect_al
and removed the restriction in gxfill.c ln 482.
This causes minor differences in rasters listed below.
3. Introduced false_stub for better readability.
This change is algorithmically equivalent.
4. Improved 2 cases in scan_contour with p.monotonic check.
The old code was wrong, but our testbase doesn't have
such cases in characters. Discovered with (2).
5. In gxttfb.c applied a curve monotonization after
decoding a True Type glyph. It allows to
apply Type 1 hints to non-monotonic stems.
This change currently is disabled.
6. Added some initializations to quiet the compiler warnings.

Fix for fonts being displayed using .notdef character (empty boxes or other
appearance). While the test file doesn't follow the PDF 1.3 or later manual
recommendations for providing a [1,0] cmap for an embedded symbolic TT font,
Adobe Acrobat Reader can display these characters. When the 'post' table
doesn't provide the glyphs required by the /Differences list, try another
cmap [3,0] to get the correct glyph (names and glyph #'s). Bug #686959 for
customer #1060.
DETAILS:
The Adobe PDF 1.4 Reference Manual has some "hints" for producing portable
PDF's, but as far as reading PDF's that don't follow these hints, all that
is said (in section 5.5.5, p.333) is:
Note: Some popular TrueType font programs contain incorrect encoding
information. Implementations of TrueType font interpreters have
evolved heuristics for dealing with such problems; those heuristics
are not described here. For maximum portability, only well-formed
TrueType font programs should be used in PDF files.
The approach of trusting the 'post' table unless the glyphs given do not
include glyphs that are mentioned in the 'prebuilt_encoding' (Differences),
is a heuristic that works for this file and doesn't interfere with any
other PDF's in the regression test. The thing about heuristics is that
the 'intelligence' they embody is no better than the understanding of the
best solution, so this may crop up again later (but we hope not).
Note that simply using the 00030000 cmap [3,0] format causes the regression
file 'test_multipage_prob.pdf' to fail with some .notdef characters.

Fix : monotonize_internal didn't work properly.
DETAILS :
We believe that the new code ever gives monotonic segments,
rather than the old one does not - see
Bug 687210 "a bug in monotonize_internal".
The new code sometimes gives slightly different segments,
because the old code applies an incorrect rounding.
This causes minor differences in rasters.

(one of them was missed by the previous patch).
2. since the intersection point isn't equal to AL_X_AT_Y value,
a special care is taken in the dropout prevention code.
3. To provide (2), moved the assignments to x_current, x_next.

and provides TT grid fitting by both coordinates.

+ 01 - Grid fit with TT interpreter; On failure warn and render unhinted.
+ 10 - Interpret in the design grid and then autohint.

EXPECTED DIFFERENCES :

Fix : Trapezoid algorithm could cause topology distortions.
DETAILS :
There were 2 types of possible distortions : inversed or self-intersecting trapezoids,
and overlapping trapezoids. Rather they are pretty rare (and a consequtive
pixel miscoverage are extremily rare), they break the topology analyzis with
the spotan device.
The distortion happen due to inprecize computations of line intersections.
The coordinate of the intersection is represented in 'fixed', which can't be
precise in most cases. Therefore the intersection point appear slightly shifted.
The harmful thing was a different shift of the same point for each of
the intersecting lines.
This patch brings 2 improvements :
1. Intersecting 2 lines, assign same X to both.
A special care is taken about vertical lines.
2. After intersections are computed, we check whether the coordinates
appear in a wrong order by X. If so, we fix it with computing the average coordinate
and assigning it to all lines. This must give a correct topology with
a small processor time expense.
Monor change : fixed some Cygwin/gcc warnings.

Raster depended on the band size (a partial fix).
DETAILS :
The old code used the Y coordinate of a top boundary of a band
as a basis for computing a sampling factor of sloped lines.
Therefore sloped lines generated "stairs" with a dependence of
the phase on the band coordinate.
This patch removes that dependence. Therefore the new banded
raster appears closer to the unbanded raster.
But the banded raster still can be different.
We don't intend to fix it now. We did only a simplest part, which
is neccessary for the current development needs.
This patch also causes some differences, which are not related to the banding.
This happens due to bands and clip boxes come to the filling algorithm
in same data field. The dependence on the clip box is dropped as well.
Particularly it affects shadings, especially radial ones.

Fix : The dropout prevention code could render an occasional raster.
DETAILS :
We discovered that the old filling algorithm has a non-well-defined behavior
when painting a group of contacting vertical stems with dropout prevention.
The result of the old code appears depending on the order of lines in the X list.
However when vertical lines have same X coordinate,
their order was occasional, and the resulting raster appears
deterministically occasional.
A new section in gxfill.c near line 1629 fixes that, see comment in there.
Another included change to a disabled code brings the curved trapezoid algorithm closer
to the uncurved one. It fixes 2 minor problems with horizontal lines.
EXPECTED DIFFERENCES :
This patch causes a minor difference in some rasters,
which we consider as progressions due to lesser dropouts.
(Well, it is arguable whether the old feature is a dropout at all,
but we'd like to have a well defined raster with no dependence
on unimportant things such as which contour point is choosen for the starting point).

Generalize the trapezoid filling algorithm for curves, step 17.
DETAILS :
This patch changes a disabled code only.
It implements the banding to the curved trapezoid algorithm.
With this patch with ppmraw with 72 dpi only 3 rasters left
different from the old code :
KozukaB-ILEmbed.pdf (1 pixel differs)
RodinCIDEmbed.pdf (3 pixels differ)
womanface.pdf (9 pixels differ)
So now the new algorithm is almost working.
An useful improvement would be to divide big curves on-fly
(it should be pretty simple with subclassing the gx_flattened_iterator
and regenerating the next curve part from entire curve by
the part index), and to replace curve_cursor with gx_flattened_iterator
in the scanline algorithm.
EXPECTED DIFFERENCES :
None.

Generalize the trapezoid filling algorithm for curves, step 15.
DETAILS :
In the enabled code this patch :
1. Refactors add_y_line into 3 functions.
2. Restructurizes end_x_line.
3. Changes the prototype of add_y_list.
4. Implements a new visual trace switch 'F'.
5. Removes 'notes' from gx_flattened_iterator.
This change is algorithmically equivalent.
In the disabled code it allows non-monotonic curves in the trapezoid algorithm.

Resolve regression differences caused by rotated page sizes being picked
instead of non-rotated in some cases. Seen with 1_pct_50_bang.pdf and
others.
DETAILS:
The 'rotate' variable was input to the 'make_adjustment_matrix' function,
but the matrix could be rotated even when rotate==0. Instead bias the
best_mismatch value when the matrix is rotated (pmat->xx == 0).

A pair of fixes to the PDF rebuild logic. The fix in pdf_main.ps corrects
a problem that ws creatd with the PDF 1.5 parser changes. The fix in
pdf_rbld.ps corrects an unbalanced stack. This was not fatal but did
leave the string (trailer) on the stack after rebuilding some PDF files.

Fix setpagedevice problems introduced with previous commit detected by the
regression tests, including 070-01.ps and many others. Also give priority
to lower value slots (match_key.value.intval)
DETAILS:
If there was a match that didn't set a new value in 'best_mismatch' (less
than the original 'LARGE' value), the match_key would be left at 'null',
causing PolicyReport to be executed. The Genoa tests use PolicyReport to
leave a value on the stack that eventually signals 'FAIL' since the count
is greater than expected.
This latest change makes sure that a valid key gets set even when the
best_mismatch value is not relevant.
The lower number slot (%MediaSource) is given priority in the case of a
tie between best_mismatch and mbest.

DETAILS :
The test file of the Bug 686875 contains a Type 1 font with 1280 glyphs,

but a limitation still presents. Will improve it someday.

Generalize the trapezoid filling algorithm for curves, step 14.
DETAILS :
This patch changes a disabled code only.
Before this patch the backward iterator works fine, but we are
unhappy of its complexity. Rather it passed the full testing
with comparefiles, a theoretical proof of its correctness is too hard.
Also it highly depends on the old code in MERGE_COLLINEAR_SEGMENTS section,
which doesnt look as a well defined code.
Therefore we went back to the implementation based on a bitmask.
It represents which points were filtered out while the forward iteration.
It consumes some bigger memory (488 bytes per active line),
but we believe that the C stack consupmtion
is still lesser than one in the Type 1 hinter.
Now we bring both implementations into a single revision,
and define a configuration macro FLATTENED_ITERATOR_BACKSCAN
for switching between them.
The KISS principle strongly votes for the bitmask implementation.
This patch also renamed CHECK_BACKSCAN_CONSISTENCY with FLATTENED_ITERATOR_SELFTEST
for a better structurization, and removed some low useful comments.
EXPECTED DIFFERENCES :
None.
Fix : Fixed a comment syntax and removed unused variables.
EXPECTED DIFFERENCES :

Fix InputAttributes initialization to have the default page size in slot
0, and all page sizes known in statusdict/.pagetypenames included with
the 'fit any' pagesize range last. Fixes bug #617077 and other files
that expect slot 0 to be a valid 2 element PageSize corresponding to the
default.
DETAILS:
As noted, "real" printer devices such as laserjets, and inkjets should
set up their own InputAttributes dictionaries that do not include the
'range' type page size.
If the page size is not an exact match (off by less than 5 points), then
the page size range will take priority. This is in a non-standard area
of Ghostscript, but must be preserved for those that want exact PageSize
such as for generating raster images of a specific dimension. If the
range page size is present, then automatic rotation will not be used.
If a PageSize is present in both orientations, such as [612 792] and
[792 612], then priorty will be given to the slot that matches without
automatic rotation.
EXPECTED DIFFERENCES:
Hopefully, none.

Generalize the trapezoid filling algorithm for curves, step 11.
DETAILS :
This patch contains a minor change to the enabled code, and
a big change to the disabled code.
The change to the enabled code only inserts some new fields
into gx_flattened_iterator, actually defining a subclass.
The enabled code doesn't use them, but provides some initialization.
The change to disabled code defines a backward iterator for
filtered flattened curve segments. Actually we define two ones :
gx_flattened_iterator__prev_filtered1 - filters points with 'coords_near'
gx_flattened_iterator__prev_filtered2 - filters points with 'coords_near' and
'gx_check_nearly_collinear'.
The forward and the backward iterators are made to enumerate same points,
which the old does while flatteining a curve. The old code has
a lot of anomalies, therefore the backward iterators appear
very coplicated. We're planning to drop the compatibility and
simplify the iterators after the curved trapezoid algorithm passes
the compatibility test.
The compilation mode CURVED_TRAPEZOID_FILL0_COMPATIBLE 1 is not completed.
Do not use it with this revision.
EXPECTED DIFFERENCES :
None.
Generalize the trapezoid filling algorithm for curves, step 10.
DETAILS :
This patch changes a disabled code only.
It removes CURVED_TRAPEZOID_FILL_SCANS_BACK because we decided to make
this feature permanent.
EXPECTED DIFFERENCES :
None.
This is the first pass at the changes to support the PDF 1.5 revisions
to the PDF format.
DETAILS:
The PDF 1.5 revision to the PDF specification contains two major
additions to the format of a PDF document. Objects can be encoded
in compressed data streams called and object streams. Xref tables
were also changed to allow the identification of objects in
object streams and also to allow the compression of xref tables.
Together these changes reduced the size of the PDF 1.5 specification
from 13.5 MB (PDF 1.4 version) to 8.7 MB (PDF 1.5 version).
pdf_main.ps and pdf_rbld.ps - The changes in these modules were for
the support of compressed XRef tables. The major part of these
changes consist of the refactoring of readxref into pieces. One
piece identifies the old format versus compressed XRef tables.
A second piece supports the reading of old format XRef tables.
The procedure readpdf15xref was added to read compressed XRef
tables. A new larray called ObjectStream was added for
identifying the location of objects which are inside a compressed
object stream. The changes for the addition of ObjectStream
also affect pdf_base.ps.
pdf_base.ps - The procedures resolveR and resolved? had to be extended
to support the presence of the objectstream type. A new procedure
called resolveobjectstream was added for resolving objects inside
of object streams.
The code listing below has two versions of the resolveobjectstream
procedure. I want to keep a record of both versions of this
procedure in CVS. The first version is theoretically more robust
than the second. It unpacks and processes objects from an object
stream one at a time. To insure that this occurs, it creates a
string of the exact size of an object and then unpacks and processes
the object. However it is also very slow. Processing of a test
document (PDF 1.5 spec.) with this routine is 4 times slower
than processing a version of the PDF 1.5 spec. which does not use
object streams. The second version of the procedure unpacks the
entire object stream and then processes each object. Thus any
problem which occurs with one object could, in theory, affect another
object. The second version is much faster. There is about a 4%
penalty for processing the compressed version of the PDF 1.5 spec.
After the initial check in, the first version of resolveobjecstream
will be removed unless some need is found for its robustness.

Fix MSVC debug targets: add explicit makefile specification.
Fix bug 687205.
DETAILS:
Debug targets have always been broken on Windows because nmake by
default looks for "MAKEFILE" and fails. Until recently, the default

This patch adds the correct filename explicitly to the debug target

Fix a premature closedevice leading to a SEGV when a setpagedevice follows
a setdevice with the only reference to the device in the graphics state.
Bug #687204 detected with ps2epsi.ps.
DETAILS:
the ps2epsi.ps sets an image device, then does a .setsafe which uses
setpagedevice to set .LockSafetyParams. Eventually setpagedevice results
in a call to gs_setdevice_no_init, but the reference count to the current
device is 1 so even though the device is not being changed, the device
was being closed (which freed the buffer and line pointers). Usually
the currentdevice reference count is > 1 since there is more than one
gstate containing a pointer to the device.
This has been broken since 8.10 when version 1.19 was released with
some changes to device finalization.
Note that ps2epsi.ps is extremely fragile and still doesn't work with
examples/alphabet.ps after the patch (due to the "clear cleardictstack
alphabetsave restore" logic at the end. This patch is ONLY for the SEGV.
IMO, ps2epsi really is a mess and needs to be scrapped and designed
properly.

Fix .gethalftone to prevent /undefinedresource or other error from being
left in the $error dict. Seen with UnusualFontMatrix.ps when running under
startjob encapsulation.
DETAILS:
Internal procedures like .gethalftone that want to use stopped but don't
propagate the error up should use .internalstopped since this doesn't
set /newerror in $error.
The file mentioned has a 'quit' following the showpage which when running
under job encapsulation (false 0 startjob) is redefined to do 'stop'.
This means that the /newerror flag in $error was being seen when the
'stop' after the showpage was executed.

Remove the CC_LEAF alternate compiler definition. This basically exists to pass
-fomit-frame-pointer (or equivalent) on a few (two) files where it's unequivocably safe. This
strikes us as premature optimization.
It was also causing problems with the profile build under gcc because of a quoting problems with
the argument list the makefile passes to itself through this define. Closes bug 687182.
In the autoconf build, only pass -O2 if the compiler is detected to be gcc. Fall back to trying
the POSIX -O in other cases. The trial compile was not detecting that this option does not work

Fix incorrect handling of the '\' escape character in the filenameforall
implementation on Windwows. Fixes bug #687151. Also fix logic in the
.scanfontdir that relied on the incorrect filenameforall implementation.
DETAILS:
The previous NT filenameforall implementation did not translate the
template string to be used by the FindFirstFile Windows call. This
meant that the template was being passed the '\' escape characters
which were not correctly handled by the OS call.
Also testing -sFONTPATH=\Winnt\Fonts showed that this was also broken
in gs_fonts.ps since it didn't duplicate the '\' characters for the
template to filenameforall.
Note that other gp_* implementations of file enumeration don't
seem to handle escapes such as gp_unifs.c. The gp_macio.c doesn't
do anything, and the gp_dosfe.c (deprecated) seems totally broken.
The gp_os2.c appears to be a clone of the gp_ntfs.c, so should be
fixed. About the only version that seems to be handling the '\'
character according to the PLRM is gp_vms.c (can you believe that?).

Simplify the filtering of points while flattening a curve.
DETAILS :
This change is algorithmically equivalent due to algebraic laws.
Thesis : (coord_near(x2, x0) && coords_in_order(x0, x1, x2)) implies
coord_near(x2, x1).
Proof:
case 1:
x0 >= x1 >= x2 ==> abs(x2 - x1) <= abs(x2 - x0);
case 2:
x0 >= x1 >= x2 ==> abs(x2 - x1) <= abs(x2 - x0);
Therefore coord_near(x2, x1) doesn't need to check and has been removed.
Same for Y.
Then merged 2 branches with '||' because they appear same.
The performance slightly increases, and the behavior is easier to understand.

Add a new compatibility header, stdint_.h. All the code previously in std.h and stdpre.h that
tried to make these types universally available has been moved to the new compatibility header
as per policy.
Generalize the trapezoid filling algorithm for curves, step 6.
DETAILS :
This change modifies a disabled code,
and includes a minor change to the enabled code,
which should be algorithmically equivalent.
In the enabled code factored out the new function add_y_line_aux.
This patch fixes the dropout problem in CURVED_TRAPEZOID_FILL 1.
The problem was unprocessed horizontal segments of curves.
Now we create a new temporary horizontal line for
each horizontal segment of a curve, and add it to the Y list.
Then it immediately goes to H list, and then processed and freed.
Due to the modification of the Y list during the main
trapezoid loop (which did not happen before) the cycle
commented with
/* Move newly active lines from y to x list. */
is improved with providing a consistency of local copies
of the Y list pointers.
Good tests for this stuff present in a.pdf .

Generalize the trapezoid filling algorithm for curves, step 5.
DETAILS :
This change modifies a disabled code only.
This patch provides more compatibility of the
CURVED_TRAPEZOID_FILL & FLATTENED_CURVE_ITERATOR0_COMPATIBLE build
to the old code. Doing it with implementing the new function
gx_flattened_curve_iterator__prev.
We're not planning to pass this function to production
because it slows down. Only reason is to simplify testing with
exact comparison of results of the old and the new code.
The macro CURVED_TRAPEZOID_FILL_SCANS_BACK helps to remove it later.
A new field skip_points is inserted into active_line_s for same purpose.
While enumerating curve segments in a backward order,
it helps to skip same division points as the old code
does in the forward order. This thing consumes too much RAM.
It won't go to production.
One problem is left unsolved. While flattening a curve,
it can generate a horizontal segment. It must be passed to h-list
for dropout prevention. It is not done yet.
This problem causes a dropout in a Chinese glyph in a.pdf
with ppmraw 72 dpi.
For a while we don't apply CURVED_TRAPEZOID_FILL for non-characters.
The reason is that pco_monotonize works imprecisely.
Will improve someday. Most characters are free of non-monotonic curves,
but we notices a number of such in Genoa tests
and in other files.
The fragment INTERTRAP_STEM_BUG is an attempt to improve a
serif suppression while dropout prevention. The coded condition
isn't perfect. It is disabled. A better way would be to depend on
Y projection contiguity, checking sect->y0, sect->y1.
Keeping it to simplify further experimenting.
EXPECTED DIFFERENCES :
None.
Fix (pdfwrite) : Type 1,2 composite glyphs could point to wrong subglyphs.
DETAILS :
This is a continuation of the recent patch for
Bug 687172 "Jaggies appearing for some characters".
The old code converted subglyph names to char codes with the font's Encoding.
However arguments of 'seac' command always encode glyphs by StandardEncoding.
If the fon't Encoding specifies different codes, the result was wrong.
Since the font copying routine uses gs_glyph values taken from the global
interpreter's space (see gsccode.h), which are PS name indices,
it needs to convert a glyph name string to a name index.
Before now we had no support for this.
To provide it we add a new graphics library callback
gs_font_dir::global_glyph_code.
A recommendation for PCL interpreter :
if it is called with pdfwrite, zfont_global_glyph_code to be implemented.
Maybe an implementation with gs_c_known_encode helps.
There exists a connected minor problem (PS interpreter only),
which this patch doesn't fix.
If a font is freed and then reloaded, the glyph names can get
different name indices, if a garbager is invoked and freed
the names before the second loading. As the result, the copied font
can embed duplicated glyph definitions (charstrings).
It can't give an invalid PDF, but it's size may increase. Hopely this case is rare.
Opening a new bug 687187 about this.
EXPECTED DIFFERENCES :

In the autoconf build, add the general cflags generated by the configure script to the definition
the the definition of CCAUX. This works around a problem building on cygwin.
DETAILS:
Older versions of cygwin do not provide stdint.h but do define some of the types in sys/types.h.
More recent versions do provide the header but also define them by inclusion in sys/types.h. This
caused a problem with the 'fixup' code we added in response to bug 687162 which defined the
missing half of the types if stdint.h was not detected by the configure script. In versions of
cygwin that do provide stdint.h, most files compile as expected, but genconf.c is compiled with
the alternate CCAUX compiler definition and was not receiving the -DHAVE_STDINT_H argument from
configure, causing a type conflict between the complete set of stdint types pulled in by
sys/types.h and the platform-specific fixup set included when stdint.h is supposedly not
available. Adding the GCFLAGS line to the definition of CCAUX works around the problem and has
little potential to confuse the build in the future.
A similar change made to unix-gcc.mak would need to document the -DHAVE_STDINT_H option for
cygwin. I felt this was unecessarily excessive; we already recommend the autoconf build on systems
that can support it.

Note that log messages of recent patches still keep the misspelled word.
EXPECTED DIFFERENCES :
None.
Generailze the trapezoid fillling algorithm for curves, step 1.
The new code is disabled with CURVED_TRAPEZIOD_FILL 0 in gx.h .
DETAILS :
This patch slightly changes the enabled code
with adding more arguments to process_h_lists and end_x_line,
and with renaming gx_flatten_sample and gx_path_is_monotonic.
The new arguments are not used with CURVED_TRAPEZIOD_FILL 0.
With CURVED_TRAPEZIOD_FILL 1 the trapezoid filling algorithm
doesn't need to faltten the path in advance, and should work faster
due to smaller number of segment allocations.
Instead the generating of flattened segments and storing them to RAM
it breaks curves into pieces on-fly with help of
the gx_flattened_curve_iterator. Meanwhile it needs "small" curves.
To provide that we generalized gx_path_is_monotonic to gx_path__check_curves,
and gx_path_add_monotonized to gx_path_copy_reducing(..., pco_small_curves).
Minor changes :
- Fixed the vd_curve macro;
- improved vdtrace calls in gxpflat.c;
- Moved the FLATTENED_CURVE_ITERATOR definition to gx.h .

Update indented preprocessor lines in code imported from Freetype to
put the '#' in the initial column, in accordance with the (slightly
more portable) Ghostscript convention.
Add a fallback definition of the common fixed-sized stdint types based on
the type sizes in the generated arch.h header. This should improve the portability
of uses of these types within the Ghostscript source.
DETAILS:
This new code in std.h does not superceed the in stdint.h and similar platform-
dependent includes in stdpre, it merely provides a fallback. stdpre.h now defines
STDINT_TYPES_DEFINED if it has done so; the std.h code is only activated if this
preprocessor symbol is not set.
This change does not help with the portability of compiling jbig2dec directly as
part of the Ghostscript build system since that code as a separate library includes
no headers from the Ghostscript tree.

Fix for 687020 and 687146. The pdfwrite device is incorrectly converting
CalRGB color spaces into ICC color spaces. Fix #1.
Details:
As Raph pointed out in the Wednesday's support call, there are actually
two problems.
1. We were not correctly recognizing that we can use a CalRGB color space
for the output. This patch corrects this problem. One of the tests in
that process was assuming an incorrect ordering to the transforms. This
fix corrects this problem.
2. The ICC color space which is being created is not equivalent to the
original CalRGB color space. This results in differing colors between
the original file and the output PDF file. This problem is still open.
Note: I am leaving these bug reports still open since problem 2 is still
open.

Factoring out the iterator for flattened curve segments.

It defines gx_flattened_curve_iterator for using in the True Type grid fitting.
The old code has bugs in the MERGE_COLLINEAR_SEGMENTS section.
An uneven behavior happened near the 'points' buffer boundary
and with the last but one point : some points were not skipped
when they should. For a while we keep a compatibility of the
new code to the old one.
This patch :
1. Defines of the gx_flattened_curve_iterator.
2. Emulates of the old code with gx_flattened_curve_iterator.
3. Provides a compatibility to the old code bugs with FLATTENED_CURVE_ITERATOR0_COMPATIBLE.
4. Improves a debug printing in the old code, to allow a trace comparizon with the new one.
5. Improves an old comment "Fast check for n == 3" ('n' was not explained).
6. Saves stack space when gx_flatten_sample recurses.

Replace the code that removes the additional CFLAGS added by the AC_PROG_CC autoconf

DETAILS:
On linux with gcc, AC_PROG_CC adds '-g -O2' to the general CFLAGS. This was overriding
the -O we add in Makefile.in, and the bug complains that this confuses gdb because of
code re-organization.
This change also means we no longer include full debug symbols in the normal build. I
don't consider this an improvement personally, but will bow to the traditionalists. Note
that 'strip' still reduces the size of the executable by 20%, so it's still worth
running if you're concerned about install-size.

This patch causes multiple differences with pdfwrite->pkmraw.
The change to pdfwrite definitely is a progression,
but it discovers a new bug 687146 "(pdfwrite) CalRGB wrongly converts to ICCBased".
We did not check which differences are coused by the new bug.

JAWS PDF generator encodes empty stream as jaws_empty[]. The stream declares
that the data block length is zero but zlib routines regard a zero length data
block to be an error. Check for this case and return EOF without calling zlib.

Fix: Adobe Acrobat Reader ignores an empty path when setting the clip
path. Bug #687136.
DETAILS:
We never encountered this problem in a 'real' file, but one of Raph's
test files showed the difference in the way our PDF interpreter handled
an zero area path to setting clipping versus the way Adobe does.
Igor tested CPSI and determined that PostScript results in a zero area
clipping box, but Acrobat Reader works differently, so the patch detects
a zero area path and does not change the clipping path in that case.
The details of the determination of 0 area is commented here:
pathbbox % get the path bounding box
3 -1 roll % roll to get upper and lower Y coordinates together
sub abs % form absolute delta Y of path bbox
3 1 roll % roll upper and lower X coordinates to TOS
sub abs % form absolute delta X of path bbox
add % sum abs delta X and abs delta Y
0 ne % if it is non-zero, then perform the clip/eoclip

Fix (pdfwrite) : Write high level clipping paths.
DETAILS :
This includes the "Preliminary patch for preserving clip path lists-bug686885" by Raph
(gxcpath.c, gzcpath.h), and a simple algorithm for writing it to PDF (gdevpdfd.c).
Now it writes entire list whenever clipping path is changed.
A diserable optimization is to avoid writing redundant elements.
For doing that we would like to have an id and a 'changed' flag in gx_path_s.

Fix : ..includecolorspace caused an abnormal recursion.
DETAILS :
1. With -dNOSUBSTDEVICECOLORS the procedure ..includecolorspace called
setcolorspace, which recursively called ..includecolorspace .
This recursion would be infinit unless an ocasional error
in a stopped context terminates it. We replace setcolorspace
with _setcolorspace_nosub to avoid the recursion.
This fixes the bug 687134 "-dNOSUBSTDEVICECOLORS causes text to disappear".
2. An optimization done with a new dictionary ..page_default_spaces,
which now keeps up to 3 global flags for Default* color spaces,
to reflect whether they were included into a current page.
It prevents redundant calls to _setcolorspace_nosub, .includecolorspace
from ..includecolorspace .
3. Moved .PurgeDict to gs_init.ps because now it is called from showpage, copypage .
4. Added a name argument to .includecolorspace and passed it through
a set of functions in the graphics library and pdfwrite.
Before that Default* color spaces were included into the PDF output
with wrong resource names.
5. Minor change : fixed a procedure header comment in gs_devcs.ps .
EXPECTED DIFFERENCES :
None, because the nightly regression doesn't test -dNOSUBSTDEVICECOLORS .
Continuation on the fix for 687101, Crash in GC on some PDF files.

Fix for 686796 tiffg4 device and incorrect halftone frequency.
This eliminates a problem with not choosing the best halftone cell size
when more than one possible cell size has the exact angle requested.
DETAILS:
Previously the logic for determing the size of the halftone cells used
the product of the error in frequency times the error in the angle as
the metric for determing the best cell size. For many common angles,
0, 45, 90, etc., this results in an angle error of zero. This then
gave a value of zero for the metric no matter what the frequency error.
The result was that in many cases we ignored cell sizes that gave a
better frequency match. The fix revies the metric to choose a cell
size which is closest (geometrically) to the ideal cell size.

Fix (font resource machinery) : Provide correct font names for graphics library.
DETAILS :
The old code passed names of substitutes rather than font names referred by a document.
This patch fixes that with adding a special ney entry /.Alias to the font dictionary.
Besides that, multiple problems are fixed in gs_fonts.ps,
some of them appeared before the repository was created.
Lising them here :
1. Several comments about stack layout in procedure headers were wrong
since the repository was created.
We repaired some of them, but possibly not all.
2. The old code assumed that SubstituteFont adds
a name to the stack rather than replaces it.
See comment inserted into .dofindfont .
The patch for the bug 637424 (Revision 1.24, Nov 21, 2002) broken the
old behavior and left multiple rudiments in code.
Now we restore the old functionality, and make SubstututeFont
to be compartible with CPSI, which replaces a name.
3. Now we define fonts for all aliases in the aliasing/substituting chain.
Not sure it is better than defining only the final one,
but the pre-repository code did so, and was
unintentionaly broken by multiple patches.
4. .stdsubstfont dropped some aliases with no strong reason.
Restoring the old behavior.
5. .tryloadfont damaged the stack balance. It was not visible due to (4).
6. We use a hack to provide the main functionality.
See comment in .aliasfont . A complete solution is too hard.
7. Inserted auxiliary comments about the stack layout.
This change fixes the bugs
687047 "fonts renamed in resulting pdf file"
687111 "Quality of output wth gs8.11 for pdfwrite device is faded as compared to gs6.12"
EXPECTED DIFFERENCES :
MANY OF pdfwrite TESTS RENDER DIFFERENTLY due to the font substitution had changed.
Now pdfwrite does not embed /NimbusMonL-Regu, but recognize its alias Courier
as a standard font name.

Fix (garbager) : The back pointer validity constraint was wrong.
DETAILS :
Bug 687021 "A crash in memory manager"
Here is what happens :
A big chunk is allocated by i_alloc_struct_array.
Later a part of the array is released.
Then another object is allocated in the released area.
Then the object is being relocated.
The old validity constraint in igc_reloc_struct_ptr assumed that the object
is in a chunk of the standard size.
However it is not.
The check fails, and gs_exit() is called.
The latter calls vm_reclaim and falls into an infinite recursion and crashes.
This patch enhances the constraint for instandard (big) chunks.
Unfortunately their sizes can't easy obtain from igc_reloc_struct_ptr,
therefore the new check only works for pointers to same chunk.
A new field (DEBUG=1 only) is inserted into gc_state_s to access the chunk from
igc_reloc_struct_ptr. We're not happy of this solution,
but there is no idea how to improve it.

Some minor clean up for the makefiles:
1. Correct lines that should start with tabs.
2. Clear some lines which only contain spaces.
Fix (PDF interpreter) : Shared CID font descriptors did not work properly.
DETAILS :
When a CID font descriptor is shared with several CID font resources,
must create several font objects with different CIDToGIDMap, DW, DW2
taken from CID font resource dictionaries.
The old code created a single font object with one randomly chosen CIDToGIDMap,
making some glyphs inaccessible, and glyphs could misplace.
New procedures adjustCIDType0, adjustCIDType2 are added into the adjustfont
dictionary, so that now CID fonts are processed in same way as fonts.
Bug 687048 "fonts not rendered correctly".
Besides that, the old code on pdf_font.ps created a CDevProc
for processing DW[2], but it was not properly added to the font dictionary and
was not executed. The new code fixes that.
This issue causes rendering differences.

EXPECTED DIFFERENCES :

Fix : Disable the grid fitting while charproc accumulation.
DETAILS :
This is a partial (minor) fix for the bug 687087 "pdfwrite : A mangled /trademark glyph".
The glyph looks fine but still converts to outline.
This change works for pdfwrite only.
It changes several files in the graphics library, but other devices
should percept this change as algorithmically equivalent.
The core of the change is explained in the comment inserted into gdevpdtt.c :
if (pdev->font3 != 0) {
/* A text operation happens while accumulating a charproc.
This is a case when source document uses a Type 3 font,
which's charproc uses another font.
Since the text operation is handled by the device,
the font isn't converting to a raster (i.e. to a bitmap font).
Disable the grid fitting for the convertion to get a proper outlines,
because the viewer resolution is not known during the accumulation.
Note we set identity CTM in pdf_text_set_cache for the accumilation,
and therefore the font may look too small while the source charproc
interpretation. The document tpc2.ps of the bug 687087 is an example.
*/
penum->device_disabled_grid_fitting = true;
}
It is implemented with defining the new field device_disabled_grid_fitting
into gs_text_enum_common.
Minor changes :
1. In gs_type1_state_s renamed charpath_flag to no_grid_fitting.
We believe the new name reflects the semantics better.
Several function prototypes changed the argument name.
2. decompose_matrix in gxttfb.c changed the prototype,
and disables the TT grid fitting for very small fonts.
(We consider it as a minor change, because currently this portion
is disabled with NEW_TT_INTERPRETER 0 in gx.h).
3. A problem discovered in t1_hinter__set_mapping that
impedes implementing a grid-fitting disabling for small Type 1,2,11 fonts.
A comment is inserted into gxhintn.c about that.
Very samll glyphs can be mangled diring a rasterization, but the mangling
isn't visible in raster with such small sizes.
Therefore the problem isn't important.
EXPECTED DIFFERENCES :
None with comparefiles.
The test file tpc2.ps of the bug 687073 doesn't cause a mangled glyph,
rather the glyph still converts to outline.
Don't cache glyphs with a suspect bounding box. The patch tests for
(urx!=0 && llx==urx) || (ury!=0 && lly==ury) but suggestions of a
better test are allways welcome.

Return correct /DeviceGray color space from currentcolorspace operator
inside PaintProc of the uncolored pattern and cache device (bug 627169).
Use igs->color_space to track the current color space.
Fix bug 687080 from customer 710.
DETAILS:
The problem in bug 687080 is definitely a conflict about the current
color space while the PaintProc is being executed. There are two
color space indicators: pgs->color_space and igs->colorspace. Most
of the time these two agree and there is no problem. However during
pattern accumulation pgs->color_space has been temporarily changed
from a pattern color space to DeviceGray. This causes a problem
when the currentcmyk operator is called. Currently, before this fix,
it calls currentcolor which returns a DeviceGray color. Then a
color to CMYK routine is called based upon the color space being
a pattern color space. This then fails since it has the wrong input
color values.
The fix looks at the current color space, in pgs->color_space,
and is special casing DeviceGray. The fix should work better than
the current logic. The only problem area would likely be if we have
other 'temporary' color spaces besides DeviceGray. I do not know of
any and the current logic would also fail.

Fix: Pattern color spaces that used save/restore within the PaintProc
would result in infinite looping with high level devices such as the
pdfwrite device since the restore cleared the pattern cache so that
after the restore, the pattern PaintProc would need to be executed
again. Bug #687052 for customer #411.
DETAILS:
The 'is_dummy' flag in the pattern cache indicates that the cache
entry does not contain bitmap or tile bits, but rather is just
a placeholder for the pattern 'id'.
The patch does not delete entries for pattern color spaces that
have is_dummy != 0. The pdfwrite device creates all pattern cache
entries as dummies.
This change does not result in any regression and, of course, prevents
the infinite looping.

Basically I prefer that switches which stop an action begin with NO.
However changing COLORSPACES to DEVICECOLORS is a definite improvement
since COLORSPACES is overly general and thus inaccurate. The only
color spaces which are substituted are the device colors.

Fix (pdfwrite) : Applying .includecolorspace to insert "default" color spaces.
DETAILS :
This completes the fix for the
bug 687054 "pdfwrite should include DefaultGray, DefaultRGB, DefaultCMYK".
The "default" color space resources are being included only if all 3 conditions are satisfied :
1. -dUseCIEColor is set;
2. -dNOSUBCOLORSPACES is set;
3. The source document defines the resource.
If the document doesn't define the resource, but the user wants to include it,
the document to be prepended with
currentglobal true setglobal
/DefaultGray /ColorSpace 2 copy findresource exch defineresource pop
/DefaultRGB /ColorSpace 2 copy findresource exch defineresource pop
/DefaultCMYK /ColorSpace 2 copy findresource exch defineresource pop
setglobal
and the resources must be available in gs/Resource/ColorSpace.
This patch removes the "default" color space resources from gs_ll3.ps,
assuming they are added to gs/Resource/ColorSpace.

Fix (PDF interpreter) : Adjust the currentpoint saved back into TextMatrix so that it
does not include the effect of TextRise.
DETAILS :
Bug 686837 "PDF with subscript rendered wrong"
Patch from Raph Levien.
Here is analyzis from Raph Levien :
[beg quote]
the test file is using PDF's Ts operator to adjust the
"text rise", exactly as shown in section 5.2.6 "Text Rise" of the
PDF manual (3rd ed). Ghostscript's rendering is incorrect because
the "settextposition" function (in pdf_ops.ps) updates the TextMatrix
using the current point after showing the text. However, this point
already contains the effect of TextRise. Then, the next time
settextmatrix is invoked, it applies TextMatrix, followed by a
second TextRise.
The patch below simply reverses the effect of TextRise before setting
TextMatrix. I believe that the correct invariant is that
"settextposition" followed by "settextstate" should result in (0, 0)
being the current point in the resulting CTM. I argue that the patch
fulfills the invariant, as follows. Let the current point be (x, y),
relative to TextSaveMatrix. Then, settextposition sets the translate
portion of TextMatrix to (x, y - TextRise). Then, settextmatrix (as
invoked from settextstate) applies TextMatrix followed by TextRise,
for a net translation of (x, y).
Query: is this reasoning still valid for arbitary rotations and scales
in TextMatrix (as set by Tm)? It seems so to me, but I believe testing
is required to establish this definitively.

Implementing a bridge to the True Type bytecode interpreter (step 19).
DETAILS :
The switch NEW_TT_INTERPRETER in gx.h is set to disable the new code.
This patch applies the design grid to emulate an infinite resolution with GridFitTT=0.
Removed changes to ttinterp.c that were inserted to that purpose.
The old code literally implemented the Raph's idea to disable the pixel rounding in the
TT interpreter. Such implementation appears not good due to a rounding may apper implicitly
while coordinate computations with low level TT operations.
The new code requires lesser changes to the TT inprepreter and needs lesser

This patch implements a new user parameter GridFitTT.
A change to documentation isn't supplied because
this code is disabled by NEW_TT_INTERPRETER 0.
Here is definition :
GridFitTT=1 forces the TT interpreter to perform a grid fitting.
If a font initialization program uses patented instrictions,
the font renders without a grid fitting, and a warning is printed to stderr.
If a font initialization program doesn't use patented instrictions,
and some glyphs of the font uses patented instructions,
the glyphs renders without a grid fitting, and a warning is printed to stderr.
If a font initialization program doesn't use patented instrictions,
and a glyph of the font doesn't use patented instructions,
the glyph renders with grid fitting, and no warning is printed.
Note that some font may mix both grid-fitted and non-grid-fitted glyphs.
GridFitTT=0 forces the TT interpreter to skip the grid fitting.
The warning about "patented" font is not printed.
The user parameter can be set by the new command line option -dGridFitTT=x,
where x is 0 or 1.

This is part of the fix for 687055. This change splits the DeviceN

DETAILS:
The DeviceN parameter SeparationOrder is used to select which separations
are to be included in the output. This parameter is not appropriate for
high level devices like pdfwrite. The pdfwrite device does not attempt
to separate its output into separations. However the pdfwrite device
does use its process color model colors for specifying output colors in
some backup cases. If a separation were missing then the it would create
an incorrect output color. By splitting out the SeparationOrder parameter
we can still use common routines for pdfwrite and other DeviceN output
devices.

Our workaround is hewristical.
To get a strongly guaranteed result a bug to be reported to Freehand,
which sets a wrong character size with setcachedevice :
the setcachedevice arguments appear 144 times bigger when the actual glyph size.
After converting to PDF it causes too big numeric errors in a PDF viewer.
Adobe Distiller converts this text into a paintings of
individual glyphs, loosing the text features, and enlarging the uncompressed output.
The Adobe's method appears acceptable with this document
because the text actually represents a texture, and the text features (Encoding, etc.)
appears unimportant. We can't implement the Adobe's method because we have no idea
how to recognize in pdfwrite the case of a Type 3 font represents a texture.
Users may want to apply an idiom recognition in PS level for that texture,
to convert it into a regular images for a better coordinate precision.
The ideom approach is independent to this patch, and we believe that
both things can work togeter.

Don't apply Type 1 hinting to charpath.
THIS IS AN INCOMPATIBLE CHANGE : charpath now creates a different outline than before.
DETAILS :
Adobe doesn't hint charpath.
Not sure why GS did.
This change makes GS to be closer to Adobe and
partially fixes the bug 687044 "strange elements with text".
Note that 'charpath fill' never was equal to 'show'. Neither the old hinter,
nor the new hinter, nor any combination of them in the pair ('charpath', 'show')
give same result. This happens because 'fill' uses the "center pixel inside" rule,
but 'show' uses a different one. With the new hinter 'show' performs
a spot topology analyzis during the rasterization. This rule doesn't belong
to the class of rules, which can be explained in terms "a part of pixel inside".
Thus, since "same" or "closer" result isn't possible,
the criterion for the choice must lie in another space.
I believe that the "Adobe compatibility" is the right one.
Besides that, Ghostscript PDF imperpreter emulates the text rendering modes 1,5,6
with 'charpath stroke', and with the hinted charpath the results look strange.

Provide a means for disabling color space substitution.
DETAILS:
Ghostscript supports substituting CIE and ICC color spaces for DeviceGray
DeviceRGB, and DeviceCMYK color spaces. This is part of the support for
the UseCIEColor feature in PostScript. This substitution is done inside
the PostScript code in lib/gs_devcs.ps.
The recent improvements to the pdfwrite device mean that the interpreter's
color space and color values are now passed to the output file. Since
the color space substitution is done prior to passing the color space to
the interpreter, the original color space is lost if UseCIEColor is
set. This change provides a means to prevent the substitution. Thus
the original color space is passed to the interpreter and on to the
output file for pdfwrite.

pdfwrite : Implement CDevProc handling for CIDFontType 2.
DETAILS :
It defines a new gs_text_process return value TEXT_PROCESS_CDEVPROC,
which allows a device to request a special interpreter callout
for executing CDevProc. The processing is some tricky :
we apply zchar_set_cache to prepare interpreter stacks,
and hook its results in pte->procs->set_cache .
This patch handles CDevProc only for CIDFontType 2.
Other font types should be a separate patch.

DETAILS :
'sclose' is inserted for a conformity, rather it has no effect in this case.
The "fixme" comment is removed because it appears wrong.
If the color space is new, it needs a complete serialization
for storing the data to PDF resource. We can't delay the serialization
because the life time of the original color space may exceed before
the next comparizon happens. Contrary, if the color space is not new,
it also needs a complete serialization for a full comparison,
to know whether it is same color space.
Thus, a complete serialization is required in any case.

Defining a new device virtual function fill_rectangle_hl_color.
This fuction is used to implement gs_rectfill and gs_fillpage
with a high level color handling.
DETAILS :
The old device virtual function fill_rectangle has no way to pass a high level color.
Therefore high level devices always used process colors with rectfill and fillpage.
See gxdevcli.h for the definition of the new function.
The new function is used to implement gs_rectfill and gs_fillpage in pdfwrite.
gs_rectfill and gs_fillpage are modified to provide the new logics.
gdevpdfd.c is reorganised with factoring out some common code parts.

Removing rudiments of the old hinter (step 1).
DETAILS :
This patch encloses rudiments of the old hinter with "#ifdef KEEP_OLD_HINTER",
where KEEP_OLD_HINTER is undefined.
This change is algorithmically equivalent,
because the new hinter worked instead the old one. Only exception is
the change to gstype1.c ln 370 : the condition t1_hinter__is_x_fitting(h)
is waeker than the old pcis->fh.use_x_hints, because
the new hinter applies an X-grid fitting with a slightly sloped transforms.
The change to gdevpsfx.c define local arrays for storing hints.
The old code used the old hinter structures, which appear too heavy
for the need of gdevpsfx.c .
Add 'extern "C"' protection to iapi.h for inclusion in C++ clients. Closes

Fix for 686948 Dotted lines messing in PDF. Draw all line cap
types for zero line lengths. Previously only rounded caps were
drawn.
DETAILS:
This is a (minor) revision to a the previous fix from Jeong for
this problem.
For those people who do not remember, this problem involves a dashed
line with a zero line length for the imaged (pen down) part of the
dashed line. Ghostscript currently calls this a degenerate situation
and does nothing except for round line caps. Jeong had previously
proposed changing the test to any line cap except butt caps. Jeong
removed this proposal after testing and finding that Adobe Acrobat
drew thin line segments even for butt line caps.
This proposal simply removes the test for line cap type completely.
It does still leaves a test for dot length = 0.
The routine already contains code for using adjacent line segments
to determine a 'direction' for zero length segments.
Testing with both butt and square line caps and with on axis and
diagonal lines produces results comparable to Adobe Acrobat.
(Acrobat is not consistent with segment widths for the butt joints.)

pdfwrite : Implementing a high level color handling.
DETAILS :
pdfwrite now passes colors identically except minor problems,
which should be fixed soon :
1. rectfill still converts colors.
This happens because gs_rectfill calls dev_proc(pdev,fill_rectangle),
which doesn't pass device color.
Therefore high level color is not available for pdfwrite.
This is an architectural problem which requires a hard decision.
2. Some documents (gs.anotherfailure.pdf is an example) generate
too many color space objects to the output PDF.
Requires an optimization.
3. 477-03.ps embeds a color space that can't write to PDF due to PDF limitations.
Process colors are written into PDF.
4. Few tests cause significant difference in colors :
0.pdf (yellow background)
MagicEye.pdf (yellow background)
Fixed_Original.pdf
Testform.v1.0.2.pdf (a gray rectangle disappears)
To be analyzed.
A preparation for high level color handling in vector devices.
THIS IS INCOMPATIBLE CHANGE for devices derived from gx_device_vector.
Now they must implement the new virtual function can_handle_hl_color.
A simplest impementation compatible to the old behavior is to return false.
DETAILS :
The new code uses the new functions gx_hld_save_color and
gx_hld_saved_color_equal instead the old gx_saved_color_update.
This allows devices to know when the client color changes and
to generate the appropriate output. This affects
pdfwrite, pswrite, epswrite, pxlmono and pxlcolor devices.
However the devices still write device colors to output.
An implementation of writing the client color
in pdfwrite, pswrite, epswrite will be the next improvement.
Since a big part of color code is shared with pxlmono and pxlcolor,
we need a switch for checking whether the device can handle
high level colors. For this purpose we add a new
virtual function can_handle_hl_color to gx_device_vector_procs.
Currently all implementation of this function return false,
and all devices still write process colors.
A minor change : psdf_setfillcolor and psdf_setstrokecolor
are removed because they were never called.
Fix decimal value of NoView annotation flag in annotvisible logic.
Fixes bug #687010.
DETAILS:
On page 493 of the PDF 1.4 reference, NoView is specified as bit
position 6, which would seem to correspond to the old value of 64.
However, for some reason Adobe counts its bit positions starting at
1, so the actual numeric value is 2^(bit pos - 1), or 32.

a non-character fill (with the path adjustment and with no dropout prevention),
character fill (with no path adjustment and with dropout prevention),
and spot topology analyzis for autohinting (no adjustment, no dropout prevention,
store trapezoids into a special storage). The ADJUST_SERIF code
probably will die after True Type hinter is done.

Cleans up the behavior of the .tempfile operator, primarily making it
consistent across all the platforms, ensuring that the TMPDIR and TEMP
environment variables are effective, the system temp directory is used
when these are not specified, and the permissions for tempfile
creation work as expected (allowed in the simple case, but closing off
potential vulnerabilities in other cases. Intended as a final fix for
bug #686922.
DETAILS:
1. The permissions behavior of .tempfile is changed so that simple
prefixes are always allowed, absolute pathname prefixes are checked
using the PermitFileWriting logic, and other cases are disallowed. In
particular, it is no longer possible to specify temp prefixes relative
to the current directory, or as subdirectories of the standard temp
directory. Both such cases are potential security holes, and are
probably not useful in any real application.
2. The meaning of gp_open_scratch_file() is made more consistent
across the platforms. In particular, it is now the clear
responsibility of this function to add the appropriate temp
directory. As such, gp_gettmpdir() is no longer exported in the public
gp.h interface (gpmisc.h is intended only for the convenience of gp_
implementations).
3. On VMS, gp_open_scratch_file() didn't previously add the
temporary directory pathname. Now it does.
4. On Windows, gp_open_scratch_file()'s behavior was somewhat
inconsistent, calling GetTempPath() only when the length of the TMPDIR
or TEMP environment variables overflowed the buffer provided. It
now additionally uses GetTempPath() in the cases where these
environment variables are not set.
5. Since gp_open_scratch_file() now takes responsibility for
determining the temporary directory, ztempfile() no longer attempts
to do this.
Convert ASCII range font names found during the FONTPATH scanning to
simole ASCII aliases (original Unicode names preserved). Fixes bug 686861
for customer 131.
DETAILS:
This is an interim patch that establishes the alias in the ASCII code
range if (and only if) the high byte of ALL characters in the name are
NULL (\000).
The future improved implementation would be to add a UTF-8 fontname when
the TTF font has the name in Unicode. This would allow simple PostScript
applications that use the 8-bit character name to work as this patch does.

Pass path across grestore using base "identity" coordinates to prevent
limitcheck errors. The upath operator returns coordinates in the current
user space, but these are no longer valid across a CTM change such as
"grestore" or "setgstate" causes. Fixes SF bug #687001 for customers
580 and 590.
DETAILS:
The patch gets the upath using identity user space, then stuffs it into
the graphics state after the grestore in the same identity space
restoring the CTM of the grestore after the uappend.
Both grestore_nopath and setgstate are modified. These could probably
be refactored later to share PS code, but the value is minimal (IMO).
Interesting that this hadn't turned up before, but two customers tripped
over this recently.

Fixes two pointers to freed objects that were left dangling
in the PDF 1.4 transparency logic. Fixes bug #686994.
DETAILS:
With some test files, saved graphics states had held on to pointers to
the device filter stack that had already been freed by a
gs_pop_device_filter() call. These dangling pointers can cause garbage
collection corruption. This patch introduces reference counting
discipline to these pointers so that the dfilter_stack objects are not
actually freed until the last reference is dropped.
A similar but simpler argument applies to the pdf14_ctx object in the
pdf14_device. This patch simply sets the pointer to NULL when freeing
the context.

with Type 3 fonts inside pdfwrite, allowing the charproc accumulation during stringwidth.

Fix for Bug 686991 Memory leak in CET test file 12-07.ps.
DETAILS:
A pointer to a free object was found while running the CET with the
memory allocation test switches (-Z@?$). The free object was a color
space and the pointer was inside a gs_image_enum_common structure.
The situation occurs when an error is found in the data source for
for an image. The actual cause was that the image enum common
structure should have also been released.
Note: The data source checking is the only place that has this
problem. After the data source checking, the image enum common
structure pointer is placed into an image enum structure. Errors
that are detected after that point call gx_image_cleanup which
handles all of the data in the image enum structure including the
image enum common structure.

Adjust internal string lengths to allow for long path/filenames such as
for Resource paths. OS limits may be shorter than the 8192 length allowed
for after this changes, but now interpreter internals won't cause a failure.
Customer 590 found this with a long GenericResourceDir. Bug #686989.
DETAILS:
While 8192 is also arbitrary, now all strings used for path/filenames are
the same and probably long enough for a while.
Also I made all the string lengths used for file copy operations be the
same 64000 bytes (they were highly inconsistent).

2. In pdf_char_widths an index for real_widths array was wrong (2 times smaller) with Type 3.

Now the precision isn't smaller than 1/100, rather the old code
looses all significant digits when a width is smaller than 1.
A better way would be re-scaling the font, but currently we don't see a strong need for that.

Add an initial outermost save unless -dNOOUTERSAVE option is specified.
Fixes Bug #686972 and others that were closed with the instructions to
use -c "save pop" prior to the file.
DETAILS:
The initial save is needed for several ProcSets from Adobe applications
and those of other vendors that expect objects in global VM to be retained
after a restore that would otherwise remove objects in global VM defined
after the corresponding save.
This kept recurring because several ProcSets from Adobe, Quark and others
expect to run under a job server. The -dNOOUTERSAVE is needed for backward
compatibility and for those that want to run under a job server and want
global VM to be restored between jobs (as expected under a job server).
Note that the save object is discarded so that it cannot be used to restore
to the state prior to .setsafe and thus circumvent security when -dNOSAFER
is used and .setsafe or .locksafe is subsequently used to go to SAFE mode.

Improve native font enumeration on MacOS. This feature is still not enabled.
DETAILS:
There are six different api calls to open a resource file on MacOS Carbon,
all of various provenance and history. We were using FSOpenResourceFile()
in our FOND parsing code because it will open the data fork of .dfont files
or the resource fork of resource font files. Very convenient. However, it
fails for some common font files with broken resource maps. Therefore we
now fall back to FSpOpenResFile() which only tries the resource fork, but
can handle the broken maps, if the first attempt fails. I've not encountered
any .dfont files with broken resource maps; they're a recent phenomenon so
we should be safe there.
Also contains changes to skip the FOND parsing for .ttf and .otf filenames,
to ask for 'Local' instead of 'Global' fonts in the enumerator (the difference
is unclear) and changes to use the Carbon headers in the Carbon build.

Read a PostScript embedded ICC input profile into a bytestring (.bigstring)
rather than a temp file. This is faster and doesn't leave the temp file
laying around. Bug #686926 for Artifex customer #1110.
DETAILS:
Since we don't know the size of the bytestring needed to invoke .bigstring,
we read the ICC profile data into an array of 64,000 byte strings, then
create the bytestring and fill it with putinterval.
This bytestring then becomes the source for a ReusableStreamDecode filter
which is a seekable filter. We'd like to have simply used SubFileDecode
filter and ASCIIHexDecode as the source for ReusableStreamDecode, but
this only works if SubFileDecode has a count.

Require python2.2 now, since the new C++ style comment checking requires it.
Initial check in of the native font enumeration mechanism with an implementation for MacOS. The
code is currently disabled pending resolution of bugs regarding some font files.
DETAILS:
This adds a trio of gp_enumerate_fonts calls which implement an interator for querying the native
operating system for font files. This is essentially required to make use of the support for
reading resource-based font collection files on MacOS since there is no convenient way to
construct a Fontmap by hand. Thus our initial implementation focusses there and only stubs are
provided on other platforms. However, it would generally be a useful feature on any system that
provides such services.
An iterator object is created with gp_enumerate_fonts_init() and released with
gp_enumerate_fonts_free(). Between these calls, each font is returned by a successive
call to gp_enumerate_fonts_next() as a pair of C strings giving the access path and reported font
name.
On MacOS these are implemented using the FMFontIterator API from Carbon. Unfortunately, while this
returns font names and files, it does not provide details about the resource internals so we must
open the file and extract the resource id corresponding to the font itself. It also is not always
possible to obtain the correct postscript name from the OS call.
Connection is made to postscript through the .getnativefonts operator, implemented in zfontenum.c.
I handles the interation and places the results on the stack as an array of two element arrays,
each representing the name and path as postscript strings. New code in gs_fonts.ps calls this and
adds the entries to the fontmap after first calling .findfontname on each path to verify
accessibility and in case the reported font name is unreliable. This is implemented as the
.buildnativefontmap procedure, which is called by the font location logic if a requested font
is not found in the Fontmap.
Caveats: This can be a very expensive operation, so like the FONTPATH directory scanning it should
probably only happen once in a given session, instead of every time a font isn't found. The macos
implementation could also be considerably streamlined.
Apparently Metrowerks CodeWarrior defines _WINDOWS_ instead of the normal __WINDOWS__. Support both for determining the calling conventions of the client api. Problem reported by Des Courtney as bug 686934.

was wrong when alpha buffer is installed with -dNOCACHE.
The patch cause difference in rendering with -dTextAlphaBits=2,4.
These cases are not tested by the regression test tool.
Minor changes :
- fixed C-style in gxhintn.c;
- removed "const gs_log2_scale_point no_scale = {0, 0}" to simplify calls
to gs_type1_interp_init.

Remove inclusions as it defines types that conflict with our
std*.h on HPUX and probably other systems. Fix for bug 686920.
Also correct the copyright dates for gxhintn.c.
DETAILS:
limits.h was defining ushort on HPUX which conflicts with the definition
imported in stdpre.h. There are two approaches within our portability
framework: don't use these defines, or make them part of the
output from genarch. Since there's only one use in the code (for
MIN_LONG) I simply defined it at the top of the file.
The test used should work on all 2's complement systems and would
probably fail miserably on anything else. It was the most portable
define I could come up with. A less assuming variant
((long)(ARCH_MAX_ULONG>>1)+1) also works but generates a warning about
the overflow.
genarch.c could of course test a variety of candidates and look for the
rollover. We could also switch to autoconf for provisioning the whole
set of defines. This was chosen as the simplest fix for the time.

Permit explicit specification of /GDBytes equal to 0 for incrementally
downloadable CIDFonts.
Fixes bug 686890 from customer 131.
DETAILS:
Incrementally downloadable CIDFont has GlyphDirectory key. According to
PLRM3 p. 376 "The binary data section of a CIDFont with a GlyphDirectory entry
does not need a charstring offset table or charstrings; if present, they will
be ignored". PLRM3 says nothing about GDBytes entry but it seems logical that
the entry is no longer needed when the structure it describes is ignored.
Old code used 0 as a default GDBytes value but required explicit specification
to be > 0. New code permits explicit 0 value because "Acrobat PDFMaker 5.0 for
Word" generates it.

Fix (pdfwrite) : Convert Type 0 fonts with multiple CID font descendents into
Type 0 fonts with single CID font descendents (the part 3).
DETAILS :
At last we got a non-degenerate test for multiple CID font descendents
and could debug this stuff with a real document.
This patch mixes several changes :
- In some cases CIDFontType 2 fonts wrongly computed glyph indices ignoring GlyphDirectory.
The new function z11_glyph_info works for it.
- The text decomposition in gdevpdtc.c mixed font indices of various font descendents.
- font->procs.get_glyph_info sometimes received glyph indices
instead glyph names or CIDs. This happened with subglyphs of a CIDFontType 2 glyph.
This patch improves the semantics of gs_glyph with distinguishing
CIDs and GIDs with a new tag in the 2nd high order bit.
The new macro GS_MAX_GLYPH_INDEX and related stuff
works for it.
- gdevpdtd.c tried to compute CID font features using glyph names,
which don't exist in this case. Replaced with CIDs.
- In gdevtrac.c a wrong glyph space was specified enumerating glyphs
(a minor change, since gdevtrac.c is almost an example).
- Fixed a compiler warning in gdevdevn.c .
Working on this patch, we can see rudiments
in pdfwrite code, which are inherited from pre-8.00 code
(before stable font copies are implemented), which to be fixed someday :
- subset_glyphs arguments in gdevpsft.c looks always NULL
and probably to be removed;
- COPY_GLYPH_BY_INDEX is now obsolete and to be removed;
- glyph enumeration procedures (*enumerate_glyph*) sometimes retrieve
a wrong tag in gs_glyph values. The new macro GS_GLYPH_TAG works against it,
rather an improvement to enumeration procedures would be useful.
The patch is debugged with korea.ps from the bug #686894.
After this change the embedded composite font with 2 CIDFontType 2
descendents is correctly decomposed into 2 Type 0 fonts with
single descendents (the old (gs8.10) code converts it into a Type 3
with outlines). The generated PDF satisfies the PDF specification
and Ghostscript can handle it. Meanwhile Acrobat Reader 4,5,6
fails with it. It appears an old known problem :
if a Type 42 font and a CIDFontType 2 with a non-standard CMap
appear in same PDF document, Acrobat Reader fails.
We believe it's a bug in Acrobat reader, because if we
modify the document with removing portions of text so that
only one of the 2 fonts is really used, Acrobat Reader renders it fine.
It fails only when both things are really used for rendering.
A workaround for this problem to do separately.
Process encryption dictionary after reading all parts of xref. Old code
resolved encryption dictionary after reading the latest part of xref only
and returned null instead of the dictionary for some files.

Add a prefix header file for the MacOS Carbon build to enable target-specific settings.
DETAILS:
Metrowerks CodeWarrior doesn't really have an equivalent of the -D commandline option to set CPP
defines at compile time. This makes it difficult to set target-specific #ifdef's, for example the
__CARBON__ switches used in the MacOS support code. The closest thing offered is a hook in the
project file for a 'prefix' header file that will be prepended to each source file as it is fed to
the preprocessor. We add such a file for the carbon build, and enable it in the project file xml.
The conditional in macgenmcpxml.sh is a direct comparison for the Ghostscript carbon shlib name,
which is excessively brittle. Something like perl's =~ /carbon/i on the target name would be
preferable, but I couldn't figure out how to do that reliably in sh.

A pair of fixes for Bug 686791 Device bitcmyk produces wrong output
The bitcmyk device produce the wrong output if GrayValues=8. In this
case the pixel size is 32 bits. The encode_color procedure was sign
extending the MSB into the upper 32 bits of 64 bit gx_color_indexes.
The fix in gdevbit.c prevents this from happening. The fix in gdevm32.c
makes it so that it does not matter. I am including both for
completeness. The bitcmyk device should not produce garbage in the
remaining bits. Thus the first fix. However there may be other
devices with this problem so I am including the fix in gdevm32.c.

Fix (pdfwrite) : Convert Type 0 fonts with multiple CID font descendents into
Type 0 fonts with single CID font descendents.
DETAILS :
Bug 686869 "Rasterized characters".
Our testbase doesn't test this case. Rather the test file for 686869
contains a font with 2 CID descendents, it actually uses only the 1st
descendent, so it's not a complete test.
The new code fails with 401-01.ps . This test file is buggy and
requires a special workaround, which should be a separate patch.
The main change is gdevpdtc.c, gdevpdtf.h .
Minor changes :
- added a new argument to a set of CMap management functions to access a
submap corresponding to a specified font index;
- gs_cmap_init now reserves so many gs_id numbers,
as many fonts it refer;
- removed some unused variables (gdevpdfm.c, gdevpdfv.c, gdevpdtb.c).
Fix (pdfwrite) : Removing the 'vdata' argument to simplify internal interfaces.
DETAILS :
This change is algorithmically equivalent.
Note that 'size' argument is replaced with 'bsize', which now passes the
buffer size rather than text size. Added some dynamical checks to ensure the
buffer size is enough.
Update changelog and history files for the 8.10 release.
DETAILS:
Turned out I'd forgotten to modify makehist.tcl to handle the new

We will also need a separate 'detailed history' file in which to archive
the Details documents before the next release.
N.B. those trying to regenerate this: the gs8_00 tag was accidentally
modified in April, so the date-from-tag filtering recommended in the

Fix (pdfwrite) : Merge the Encoding of the 'complete' font copy when merging fonts.
DETAILS :
"PPI-ProPag 2.6.1.4 (archivePg)" creates multiple font copies with reduced encodings
(we believe it is poorly designed), and we merge the copies back to a single font.
Doing so the Encoding was not merged for the "complete" font copy.
The patch fixes that.

Fix (pdfwrite) : 'loca' was wrong in some cases embedding a TT font subset.
DETAILS :
By TT spec, when a TT font uses indexToLocFormat==0, glyph offsets in 'glyf' must be even.
The old code doesn't take care about the glyph alignment while converting a font
from indexToLocFormat==1 to indexToLocFormat==0.
This patch inserts padding bytes into 'glyf' to align glyph offsets with indexToLocFormat==0.

1. Ignore data after %%EOF whicl scanning for objects or trailer.
2. Allow objects with duplicate object and generation numbers.
3. Change heuristic for finding the trailer dictionary.
DETAILS:
The previous testing had on the rebuild facility had verified that
all test files ran without apparent problems. However a full check
of the files in the regression test suite has found three cases of
the output images not matching between the normal PDF processing
and the rebuild processing.
1. Many real life PDF files contain garbage after the final %%EOF
marker. Ghostscript has known about and tolerated this situation for
some time. I found a test case (adesso6.pdf) in which the repair
logic was finding what it considered a valid object in this garbage.
The revisions determine the location of the last %%EOF and form a
count of the data left in the file after the %%EOF. This count is
used to exclude this data from the object scanning and the trailer
location scanning.
2. A test case was found in which two objects were found to have
the same object number and revision number. By my reading of the
PDF spec, the newer object should have a higher revision number.
However the object scanner was changed to accept the last such
object as the desired one. Most PDF editors (at least Adobe) put
updated objects at the end of the file.
3. A test case was found in which a Linearized PDF file had been
edited and a new xref list and trailer dictionary were placed at
the end of the file. The heuristic for finding the trailer dictionary
was changed to check the specified location of the 'first' xref list.
If this location is in the first half of the file, then the start of
the file is searched for the first trailer. Otherwise the end of the
file is searched for the last trailer.
With these three changes, all of the PDF files in the regression
test suite produce matching results using either the normal PDF
processing or the rebuild procedures.

The TrueType font loading was quite a bit slower than it should be. This
optimized font loader is up to ten times faster. Fixes bug #686851.
DETAILS:
Analysis of the time spent during TT font loading led to two problem areas.
The first was that the cmap array was built inefficiently when their was
a large glyph range, that had large holes was built with a loop that
called a PostScript function 'putglyph' to fill unused areas with .notdef
(glyph ID 0). The revision pre-fills the 'glyphs' array with .notdef from
a static array pre-filled with 1024 zeroes.
The second problem was the code that built the encoding using the 'post'
table. This code had a 'repeat' loop to find the name from the start of
the glyphNames section of the 'post' table for each named glyph in the
encoding. By creating a temporary cross reference, only one pass through
the names is made.

Correct the implementation of the new file_name_combine operators for MacOS.
Details:
The parent directory reference prefix is '::' rather than ':'. Also, a path
that begins with the ':' directory separator is a relative path from the
current working directory.
The more substantive change is in the implementation on gp_check_root(), intended
to return the 'root' prefix of a path, if any. The previous implementation returned
the location of the first patch separator, causing initialization to fail when
attempting to determine if GenericResourceDir ends in a directory separator in
gs_res.c.
Absolute paths are not a well defined concept on Classic MacOS. In that case we just
return 0, as if no path were ever absolute. This likely causes other problems not
addressed here. In the Carbon build, we make use of the FSGetVolumeInfo() call
to enumerate all mounted volumes, attempting to match each one. This call returns a
16-bit char unicode name for each volume which we make no attempt to convert to
whatever 8-bit encoding ghostscript might receive the path in orginally; however
we do match the lower 8 bits for the first 256 characters, which works well enough
for English volume names.
Note that this patch only provides support for MacOS-style paths with ':' as a
separator. The Metrowerks Standard Library also accepts unix-style paths and
on MacOS X users will expect to be able to use them. Support will need to be
extended to include this.

This is a set of routines for attempting to recover PDF files which
have been mangled by EOL conversions. This is a facility which Adobe
Acrobat has and thus we need to duplicate.
DETAILS:
THE PROBLEM:
The basic problem is that PDF files contain 'xref tables' which are
really object location indexes which contain the absolute position of
objects in a file. If a file is changed by converting the type of
EOLs then the file size is changed and the xref data is no longer
valid. In many cases, Acrobat can rebuild these files. It is not
always possible to always rebuild files. If the files contain binary
data which contains line feed or new line characters then the binary
data may be mangled and cannot be rebuilt. We need to be able to
duplicate Acrobat's ability for rebuilding files. (Note: In theory
one can get more and more sophisticated about rebuilding files. The
techniques used in this code are quite simple but effective.)
THE BASIC SOLUTION:
The solution to this problem consists of several pieces. The first piece
was to modify the pdf interpreter's internal representation of the xref
data. The xref data is stored into two larrays. The larray Generations
contains the object's generation number. This was not changed. The
larray Objects contained the location of the xref entry in the file.
This was set initially by the readxref routine. Since the xref entry
data is not valid (for mangled files) this was not useful. Objects
was changed to contain the actual location of the object in the file.
This actually eliminates one step in the process. Previously when an
object was referenced, the location of the xref entry in the file was
obtained from Objects and then the xref entry was read to determine
the actual location of the desired object.
The second part of the process was to put .internal_stopped trapping
around the two usages of readxref to catch any failures of that routine.
An error message is printed and we then try to rebuild the locations
of the objects and find the proper trailer dictionary.
The third part of the process is to locate the objects in the file.
This is done by a simple scan of the file looking for lines beginning
with x y obj where x is a object number and y is object generation
number and obj is the text 'obj'. In theory this simple strategy can
be confused by binary data but with over 156 files tested, no problems
were found.
The fourth part of the process is to locate the appropriate 'trailer'
dictionary. There is a trailer dictionary with each xref list. In
theory there can be many trailer dictionaries in a file. The only
desired trailer dictionary is the one associated with the 'first'
xref list. Unfortunately since we cannot count on the location
information in a mangled file, following the xref links is problematic.
The solution used is simple. For Linearized pdf files, we find the
first (at the front of the file) trailer dictionary otherwise we use
the last trailer dictionary in the file. This simple method works
for the 151 known good files (see testing below) and all five known
bad files.
Included are diffs for the changes and the new file lib/pdf_rbld.ps.
The only change in the src directory was the addition of pdf_rbld.ps
to the int.mak file.
TESTING:
There have been two sets of test run on this code. The first set
consists of running 151 pdf files from our regression test suite.
These files are not mangled. However by disabling the normal readxref
routine, the new code was exercised. All 151 pdf files were displayed
correctly.
The second set of tests consists of actual problem files. I was able
to locate five files that we have been sent that have been mangled.
file name Ghostscript Acrobat 5.0.5
1003.pdf okay okay
cm_test.pdf okay okay
precon.pdf okay fail
ServletReport.pdf fail fail
dauben.pdf fail fail
As expected, not all files can be recovered. I was pleased that,
for this small sample, we did better than Acrobat.
Revised fix for 686872 token operator sometimes leaves extra data on stack.
With some strings, the token operator can leave extra data on the stack.
In the test case, the token operator is generating a syntaxerror. The
error is expected. However the token operator is leaving 3 items on the
stack. It should only leave one: The original string. This fix
corrects the problem.
DETAILS:
The problem was found while developing the xref data recovery facility
which uses the token operator to scan PDF files (including binary data).
The fix consists of simply recording the operator stack level at the
start of the string processing and restoring it if an error occurs.
The revision to the fix consists of using the 'pop' macro to modify
the o_stack pointer instead of directly setting the pointer.

Log message:
For the pngalpha device, set the default background color to white
in the bKGD chunk. Add an option -dBackgroundColor=16#RRGGBB to
explicitly set the background color. This is needed by a common
web browser that doesn't correctly support PNG with alpha transparency.
DETAILS:
Programs that don't fully support alpha transparency let
libpng convert an RGBA image to RGB. The background color
used is either provided by the program, or in the bKGD
chunk, or it falls back to gray. MSIE was defaulting
to a gray background which is not commonly used on web
pages. By writing a white bKGD chunk, PNG files will display
correctly against a white background in MSIE.
If a solid color for a web page background is used
with , then PNG images appearing
on that page would need to be created with
-dBackgroundColor=16#CCCC00.
For textured background there is no hope.

Fix for 686857 bitcmyk has problems with -dBITS=2. This fix corrects

DETAILS:
This problem was caused by a change (1.2) to src/gxdevndi.c
src/gxdevndi.c
Modified gx_render_device_DeviceN to always perform the conversion
from color component intensity values to halftone levels in an
additive sense, if the gray_colorspace operand is true. This is
necessary for compatibility with the pre-DeviceN code.
However the change only worked for max_value = 1. This is the typical
case of 1 bit halftoning. The fix works for any value of max_value.

If reopening the display device fails after setting the
callback, display an error message. Allocate the large display
bitmap using a low level allocator to avoid exceeding the memory
limit of the previously used device stable memory allocator.
Fixes bugs 686836 "-r doesn't work" and duplicate 686838
"Ghostscript doesn't do anything".
DETAILS:
The display memory device and the raster including line pointers
was allocated using the stable allocator of the display device.
This had a limit of 1Mbyte, which was exceeded when the
resolution was greater then 114dpi. This would cause subsequent
allocations to fail, but it appears that nothing else tried to
use this allocator after the display device. The display device
was changed to allocate the line pointers separately to allow
the raster to be allocated in special memory, e.g. video memory
or shared memory. This caused the subsequent allocation of the
line pointers to fail when resolution exceeded 114dpi.
The modified code now allocates the raster with
gs_alloc_byte_array_immovable, which allocates directly from the
C heap, not subject to any memory limit apart from the overall
-K limit if specified, and is not subject to garbage collection.
The normal allocator now has sufficient memory to allocate the
line pointers without problem. The raster pointer is removed
from the pointers that are enumerated during garbage collection.

-sDEVICE=x11cmyk. This fix increases the stack checking while sampling
tint transform functions. It also makes the error handling more robust
for invalid tint transforms.
DETAILS:
It is sad to say but this is a bug that we have seen before, several
times. Ray and I fixed this problem at the last code fest in September.
However that fix did not make its way into CVS.
The cause of this problem is that certain proc sets from Adobe violate
the PLRM. In the test file, the proc set is from Adobe Photoshop
Version 5.5. The proce set contains tint transform functions which
violate the specification in two different ways. In one case, the tint
transform function changes stack values outside of the given color value.
This is used as a test to see if the interpreter supports the given
duotone color space. If so then the proc set creates a color space with
a tint transform which is unbalanced in its stack usage. This could
cause a stack overflow/underflow during sampling of the tint transform.
Adobe apparently assumes that this tint transform is never executed
since the function starts with the name /NeverReached.
The fix involves checking the stack depth after each execution of the
tint transform function and verifying that it matches the correct
position given the number of function inputs and outputs. If so then
the stack is returned to its original position and the sampling is
aborted. Changes in lib/gs_sepr.ps make the tint transform sampling
logic more robust in case the tint transform modifies the top of the
stack. (This occurs in this case since the tint transform is actually
popping extra items off of the stack.) We also create a dummy tint
transform function if sampling fails. The later was done to prevent
the /typecheck error and give pdfwrite something with which to work.

Fix scanline size calculations and channel mix-up.
Following PDF 1.4, chapter 4.6.2 pattern is instantiated in the graphic state
harvested at the beginning of the pattern's parent content stream. This patch
fixes PS graphic state parameters only. PDF specific parameters are still
inherited from the current graphic state.
Bug #686834
DETAILS:
PS makepattern operator saves only PS graphic state for later use in PaintProc.
GS PDF interpreter implements PDF graphic state as a stack of dictionaries.
We should save full PDF graphic state and set it manually during execution of
PaintProc.

Add processing of %%BeginICCProfile DSC section for (some) EPS file, notably
Adobe Photoshop. Final part of fix for bug 686797.
DETAILS:
The change to gs_pdfwr.ps was due to the fact that it did not properly
balance the stack.
The method of trying /N 4 + /DeviceCMYK, then /N 3 + /DeviceRGB, finally
/N 1 + /DeviceGray is a *hack* that could be avoided if we knew what color
space the ICC profile expected. Since .seticcspace fails if /N doesn't
match what is in the profile, this seems like a reasonable hack.

A preparation for non-convert PatternType 1 to rasters with pdfwrite.
DETAILS:
The patch defines a new device virtual function pattern_manage,
and a default implementation for it. The purpose is to inform
the device about pattern accumulation and to bypass the installation of
gx_device_pattern_accum when the device can handle the pattern command stream.
The new code is temporary disabled with PATTERN_STREAM_ACCUMULATION 0
macro defined in gx.h . When it is 0, the new device virtual
function is provided but never called. The behavior should not change.
The rest of this log message describes PATTERN_STREAM_ACCUMULATION 1.
In this mode pdfwrite doesn't convert PatternType 1 to rasters.
It creates good PDFs at least with 012-09.ps and 269-01.ps
(these are very complicated cases with patterns inside charprocs and patterns),
but there are problems when rasterizing the resulting PDFs with GS.
(A new bug 686834 issued for tracking this problem).
When a pattern stream is handled by the device,
we can't create a proper content of gx_color_tile.
However we need a correct content if the pattern is used
for rasterization of an object which the device can't handle
at the high level. An example is pdf14 device during a PDF re-distillation,
which handles transparency. Another example is
a conversion of composite fonts, which have multiple CID descendents -
pdfwrite still converts such fonts to raster fonts.
Since a proper contents may be needed for gx_device_color,
we define a new flag gx_color_tile::is_dummy, and account it in
gx_pattern_cache_lookup. Thus, if the current device is cache device
installed for the font conversion, the tiles with is_dummy == true
are being be dismissed. Vice versa, tiles with is_dummy == false are
being dismissed when current device is pdfwrite.
We do not move parts of zpcolor.c code to gx_default_pattern_manage,
because we don't see a proper place for it to be compatible to
the FEATURE_DEVS configurability. Instead that, we implement
a branching inside gsptype1.c and zpcolor.c . If more branches will
be necessary in future, this to be improved with moving code
fragments to specific implementations of pattern_manage,
together with improving the FEATURE_DEVS modularity.
Delaying this reorganization until a strong reason appears.
NOTE: The patch extends the device interface with gs_pattern1_instance_t.
Minor Changes :
1. Fixed some MSVC warnings.
2. gx_pattern_alloc_cache passed a wrong client ID to memory manager.
3. Skipped some unuseful graphic state parameters while a contents substream accumulation.
In the display device, store the line pointers separately from
the bits, so that the bits can be placed in special memory (e.g.
allocated in video memory). Fixes Bug 686780 display_memalloc()
asks for too much memory.

Calling the gsapi polling function from the Macintosh gp_check_interrupts
function voilates the layering of the interpreter over the graphics library.
Therefore we isolate the offending code to a separate module 'macpoll.dev'

Call the gsapi polling function during the main interpreter loop
timeslice code. This allows a client to abort the interpreter
when running "{} loop". Fixes Bug 686810 "CHECK_INTERRUPTS
should allow shorter worst-case abort".
DETAILS:
PostScript which executed an infinite loop could not be stopped
by the gsapi client. The time slice code in the main
interpreter loop is executed once for every 32767 passes through
the interpreter loop. Within the time slice code we now call
the polling function and if the return value is non-zero, we set
code to gs_error_interrupt to cause the interpreter to exit.
This was not a client bug (as far as I know). The original
request was from Zoltan Biro.

DETAILS:
The jbig2dec library and headers require some of the C99 types. We've

passing -DHAVE_STDINT_H on the commandline or windows-specific typedefs.

Fix (pdfwrite) : Compress charproc streams.
DETAILS:
This patch mixes 3 changes :
1. Applying a compression to vector charprocs. Bitmap charprocs are
left uncompresed. The written PDF should have same contents as before.
2. A preparation to Type 1 pattern accumulation with implementing
a pdf_substream_save stack. Moved accum_char_proc_* fields to there.
This change should be equivalent.
3. Renamed cos_write_stream_from_pipeline to cos_stream_from_pipeline,
because the old name appears confusable.
A new function with the old name is defined for another purpose.
No regression changes expected.
Fix (pdfwrite) : Use cos_write_stream for charproc accumulation.
DETAILS:
pdfwrite crashes with -r72 012-09.ps due to 2 nesting separates :
one for charproc accumulator, and another one for graphic state object inside it.
This problem does not happen with comparefiles with the default value of -r.
Meanwhile the problem is harmful because it occasionally depends on CTM.
Minor changes :
- A misprint in "pdf_begin_char_proc_gerneric".
- Removed some unused variables.
- Inserted some necessary #include statements.
Fix (dropout prevention) : sfill was unintentionally slowed down.
DETAILS:
In some cases the scanline algorithm appears to speed up the sfill in about 2 times.
This patch enables the scanline algorithm when DROPOUT_PREVENTION is on,
except for characters. It brings the shfill case closer to the old algorithm.
This patch causes minor differences while filling a path,
especially with shfill, but such differences should be small
and almost unvisible.
Minor change :
The condition in gxfill.c line 2075 is changed to be closer to
the old algorithm when filling non-characters, because
dropout prewvention is not neccessary for this case.

Fix (pdfwrite) : Generate pseudo-random font names for subset fonts

Bug 686807 A "subset fonts" error in Adobe Acrobat from files made by GS8.00
DETAILS :
Since the revision 1.9 of gdevpdtb.c (Sun Sep 8 20:20:12 2002 UTC)
subset font names were deterministic to simplify the debugging.
The names were derived from resource IDs, and could cause a conflict
when merging documents. This patch generates different font names
hashing the glyph usage bitmask. Now the conflict can happen
with a very small probablility, when different subsets give same
hash value.

Switching to the new logics of resource file location.
THIS IS INCOMPATIBLE CHANGE, because the default resource path is now different :
resource files are moved to gs/Resource .
See gs/doc/Use.htm#Finding_files and gs/doc/Use.htm#Resource_related_parameters.
DETAILS:
This patch does not include necessary changes to Ghostscript installer.
The main code change in one to gp.h .
Rudiments of old code in gs/src and gs/lib are marked with NEW_COMBINE_PATH.
They to be removed after beta-testing.
Change to makefiles provide extended default values for
file search paths, which are platform dependent.
For convenience, here we summarize all related issues,
which were mentioned in previous patches :
1. The search method with multiple resource directories
appears not fully conforming to PLRM. We cannot ever call
ResourceFileName while executing findresource
or resourcestatus, because per PLRM it always
returns a single path. Therefore we implement
an extended search method in findresource,
resourcestatus and resourceforall, which first calls
ResourceFileName and checks whether the returned path
points to an existing file. If yes, the file is used,
othervise we search all directories specified in
LIB_PATH. With a single resource directory
it appears equivalent to Adobe.
THIS IS INCOMPATIBLE CHANGE.
2. ResourceFileName may be used for obtaining a path
where a resource file to be installed. In this case
Ghostscript to be invoked with -sGenericResourceDir=path,
specifying an absolute path. The default value for
GenericResourceDir is a relative path. Therefore
a default invocation with a Postscript installer
will install resources into gs/Resource.
THIS IS INCOMPATIBLE CHANGE.
3. We do not distinguish lib and Resource directories.
There is no file name conflicts because
lib does not contain subdirectories, but Resource
always store files in subdirectories.
4. We implement a new flag in gs_context_state,
which informs lib_file_open whether it is invoked
with a file specified in a command line argument.
Doing so because command line argument files
don't need to check permissions, and they
are executed with a special PS operator .runfile .
We cannot use a .runfile argument for passing this
information, because it would be a security hole
due to .runfile is available for documents
and cannot be hidden.
5. We still have a security hole while loading
resources from gs_init.ps .
Both the old and the new code load some resources
(such as CIDInit ProcSet) before entering
the SAFER mode. Therefore it is a way for
Postscript viruses to migrate.
To be fixed later.
6. Default values for GenericResourceDir and FontResourceDir
are platform dependent.
(The old code always use Unix notation - a bug).
7. Default value for GenericResourcePathSep is platform dependent.
The value is used before non-directory items only.
(The old code always use Unix notation - a bug).
(The old code used the value before directory items - a bug on OpenVMS).
8. If a path starts with a number of parent references,
a template with same number of parent references
must be added to permission list to allow the access in SAFER mode.
The template (*) allows access to any file.
THIS IS INCOMPATIBLE CHANGE, because
the old code ever rejects parent directories.
9. GenericResourceDir and FontResourceDir are not being added
to permission list while .locksafe. Instead that,
we generate (*/*) templates with all LIBPATH items.
THIS IS INCOMPATIBLE CHANGE, but for non-exotic cases
(such as "(./Resource/CMap/H) .libfile" in a document)
it should not be visible.
A. Scratch files with a non-absolute prefix always open
in a scratch directory. The old code can open them
in current and parent directories if an user modified
a default prefix in C code.
THIS IS INCOMPATIBLE CHANGE for users who had modified
a scratch file prefix in C code.
Permission for scratch directory is not checked
as well as in old code.
B. The operator .filenamedirseparator is removed,
because it cannot work properly on OpenVMS.
On OpenVMS it needs both prefix and trailer to
determine a correct separator.
We removed it because the new logics never needs it.
C. The operator .pathstring_not_bare is removed,
because .file_name_combine performs it's job better.
D. The functions gp_pathstring_not_bare, gp_file_name_references_parent,
char *gp_file_name_concat_string are removed.
E. New operators added to maintain the new logics :
.file_name_combine true
.file_name_combine false
Combine a file name with a prefix.
The first argument is a prefix, the second is a file name.
Internal syntax of arguments and result is platform dependent.
The combination is being reduced to a shortest equivalent,
but if it starts with cwd reference, the starting
cwd reference persists.
If the argument is true, it considered to use the
"no sibling" mode. It prevents reduction of
(x/../y) to (y) for any x != y. With false such reduction
is allowed. The argument appears a rudinemt from
a dead branch. The new code always sets it to false.
On success, the result is a combined, reduced path and false.
On failure, the argument strings left on operand stack,
followed with false.
- .file_name_separator
Returns a readonly string, which represents a separator
which is used in file names between directory item and file item.
Used for making the default value of GenericResourcePathSep.
- .file_name_directory_separator
Returns a readonly string, which represents a separator
which is used in file names between two directory items.
Used for making the default value of GenericResourceDir
and FontResourceDir.
- .file_name_current
Returns a readonly string, which represents a reference
to current working directory. Used for making the default
value of GenericResourceDir and FontResourceDir.
Removing it because it appears in a wrong place of the directory tree.

Use fstat() function to determine whether the file is seekable.
This should work on all supported platforms and seems to be the only way
to get the file type using a MSVC CRTL function.
Bug #686773
DETAILS:
Windows API documentation seems to imply undefined results when seeking
of retrieving file position of a special file. MSDN documentation requires
programmers to check file type using GetFileType() function before seeking.
MSVC 6 CRTL doesn't check file type before calling the corresponding
Windows API functions. fstat() is the only function in MSVC 6 CRTL that
calls GetFileType(). S_ISREG() is a POSIX macro that check whether the
file is ordinary. It can be easily emulated if missing.

Add news script to generate split abbreviated/detailed changelogs in the new
format. Accepts xml input from the cvs2cl perl script.
DETAILS:
After the 8.00 release we switched to a new format for Changes.htm and the
History files, based on the more traditional Changelog format instead of
grouping commits by section, which often resulted in duplicate posts. At
the same time we began a convention of including any notes too extensive
for such a listing below a 'DETAILS:' separator, with the idea that we'd
create two changelogs, with hyperlinks between so detailed information was
still available even in the new easier to browse format.
The method we've adopted uses the cvs2cl perl script, available from
http://www.red-bean.com/cvs2cl/ to parse the output of 'cvs log' and
generate an xml file containing the merged entries. This script is
more robust than our own cvs2hist. The split_changelog.py script is
then run to convert the xml changelog to the two sizes of linked html
changelogs.
split_changelog isn't very bright about constructing links, so it should
be run from inside the doc directory for now.

sets a special mode for graphic handlers.
We ever clip BuildChar/BuildGlyph with a FontBBox or with character bbox
specified in setcachedevice*. Doing so with calling gx_clip_to_rectangle
from pdf_text_set_cache, because we need to avoid the
current PS clipping path to interfere the character proc.
Possibly a better way is to install an infinite (i.e. absenting) clipping box,
wnen setcharwidth is used instead setcachedevice*.
but we don't know how to. Due to that the distilled 238-01.ps
renders some differently than undistilled one, and in most cases
it appears closer to what CPSI does.
An additional optimization : In sync_text_state the condition for matrix
sinchronization is done weaker : with empty text buffer the
synchronization is not needed.

Initial commit of native MacOS font loading. This implements a %macresource% iodevice for
retrieving data from the 'resource' structure associated with MacOS files, either directly from
the resource fork, or from a serialized data fork resource file. This is primarily used to access
font data on that platform. Resource fork access is only supported on MacOS, while data fork files
(e.g. .dfont format font files) can be read on any platform. This code is currently disabled.
DETAILS:
This change allows fonts stored in resources to be specified in the fontmap. A special indexing
scheme is added to the filename to address the particular resource desired by id and 4-character
type code, e.g. '%macresource%Arial#sfnt+4096' or
'%macresource%/Library/Fonts/Optima.dfont#sfnt+14151'.

Remove the non-HAVE_STDINT_H non-win32 attempts to define stdint types
and related sys/types redefine hacks. Also warn in the configure script
if stdint.h is not found.
DETAILS:
Compiling libjbig2dec requires the size-specific types in stdint.h, as
does compiling in the headers. Therefore these types must be made
available in ghostscript if jbig2.dev is included in FEATURE_DEVS.
The best way to integrate this is to create a stdint_.h for ghostscript
that contains discovered and/or platform-specific typedefs for the
types. This is still the plan, but to speed integration we just through
some defines into stdpre.h. If -DHAVE_CONFIG_H is passed by the makefile
(as configure does) then the C99 header is used, and we make specific
defines for MSVC which doesn't yet ship the header. We also had some
fallbacks for other systems (vendor unix mostly) but these caused
collisions with partial definitions of what became the C99 types in
sys/types.h and the redirection hack we do with ulong et al. did not
work on all platforms (notably macosx).
It is the fallback defines that have been removed; users building
on older platforms will probably have to patch the types in to use JBIG2
support.

Prevent UMRs and when an image3x type image only has one of the possible
two masks. Hangs or data garbling could result. Related to bug #686782.
DETAILS:
While several places in the image3x handling checked mask[i].depth to make
sure that it was non-zero, other places didn't have this check, but just
operated on the InterleaveType of the mask. While I could have added the
mask[i].depth check, setting mask[i].InterleaveType to zero when a mask
was not used was a single line change and served the purpose.
I found this when looking at performance on this PC_*.ai file and was
getting infinite loops. The plane_data was ending up pointing to the
wrong area when the uninitialized mask[i].InterleaveType just happened to
be 3 (interleave_separate_sources).

pdfwrite : The old code copied parameters of PS interpreter's graphic state
to the output PDF. However some of them are installation dependent and must not copy.
THIS IS AN INCOMPATIBLE CHANGE : the generated PDFs will render some differently
on printers.
DETAILS:
We provide a signal to pdfwrite at very end of gs_init.ps - see
the change to gs_pdfwr.ps, the priority=2000.
The signal is handled in gdev_pdf_fill_path,
and stores a copy of PS interpreter's graphic state parameter values.
Those valuess are used for comparizon with current parameters of PS interpreter
when an object is written. Therefore, if a value of a parameter was not
changed by a document, it is not written to PDF.
Note that if a PS document sets parameters equal to the
installation defaults, the setting in missed in PDF.
This is unfortunate.
The patch causes multiple differences in rendering distilled
comparefiles with pkmraw, because transfer functions changed from a
HP-specific (defined in gs_init.ps) to none. Those differences were
checked with the fuzzy compare utility and look fine. It should fix
the 2003-03-26 regressions, but new differences will appear.

Fixing some compiler warnings (unused variables, etc.).
Fix (pdfwrite) : Provide a complete monitoring of the viewer's graphic state
while generating a PDF output. The old code misses the synchronization
of the viewer's graphic state with its internal copy when generating
a 'grestore' command to undo a clipping.
Bug 686763 "pdfwrite is not correctly handling OPM distiller parameter".
DETAILS :
This change affects all vector devices, but it should be equivalent
for all them except pdfwrite, and except for the pointer lifetime bug
explained below.
Here is an example when the desynchronization appears :
f1 settransfer
0 setcolor
path1 fill
f2 settransfer
1 setcolor
path2 fill
gsave
path3 clip
path4 fill
grestore
path5 fill
After 'grestore' it uses f1 instead f2.
The old code does not remember the viewer's graphic state,
which was immediately before 'gsave', and resets the internal copy of
the graphic state to default values when it generates 'grestore'.
This logic is fully wrong : if after 'grestore' a parameter is equal
to the default value, pdfwrite does not generate a set command for this parameter,
but the viewer uses the value which was set before 'grestore',
which can differ from the default one.
Moreover, gdevvec copies the device color from local memory
to global memory, and doesn't ask garbager to process pointers in
the copy. When the device color contains pointers
to patterns or so, the live time of the copy appears bigger
than the live time of the pointed structure. The old code only
compares the pointed addresses without accessing the pointed data,
so that a crash can't happen. But if garbager moves another color
to same address, the comparison answers "equal" when actually colors
are not equal, and the generated PDF appears wrong.
To exclude the pointer lifetime problem, the patch uses the 'save_dc' method
instead the 'equal' method for colors. But the implementation
of save_dc was dummy for patterns. To complete it, gs_id is
inserted into gs_pattern_instance_s, and more variants added to
gx_device_color_saved_s. The clist device appears tolerant
to this change.
Note that macros color_unset, color_set_null, color_is_null,
gx_dc_is_null are now applied to gx_device_color_saved.
For complete monitoring the viewer's graphic state,
we implement a 2-elements stack 'vgstack' in gx_device_pdf_s,
save the viewer's graphic state in it when generating 'q' commands,
and restore from there when generating 'Q'. If a 'gs' parameter
needs to change, we move to 'PDF_IN_STREAM' context, because
we must not insert 'gs' into a text context. New functions
pdf_try_prepare_stroke and pdf_try_prepare_fill provide
the "try" logics for this.
If a 'gs' parameter changes with changing a clipping,
first we need to undo the old clipping with 'Q',
and then generate new 'gs' parameters relatively to the
restored graphic state. The new function pdf_unclip
works for this.
With this patch the length of generated PDF appears longer
for some tests. The most important ones are :
acrobat.pdf Lengths differ in 6141.
adesso8.pdf Lengths differ in -8316.
HeiseiMinStd.pdf Lengths differ in 4000.
narrow_font.pdf Lengths differ in 6141.
RealCities.pdf Lengths differ in 12370.
RodinCIDEmbed.pdf Lengths differ in 101698.
It happens because pdfwrite doesn't remember 'gs' dictionaries,
and therefore redundant copies can appear.
This problem to be fixed separately.
Expecting a progression : 093-01.ps (was a wrong stroke widths with a PaintType 2 font).
Expecting a regression : with this patch, re-distilled
Testform.v1.0.2.pdf paints good with Adobe, but wrongly with GS.
Maybe a bug in GS PDF interpreter.

Implements raster database to store and retrieve cached baseline rasters.
Define some of the C99 stdint types in the common stdpre.h. This is
required for libjbig2 integration.
DETAILS:
Another option would have been to define a local 'stdint_.h', but
stdpre.h already contains a number of typedefs and includes sys/types.h
to provide expected basic types. We use stdint.h itself if the toplevel
makefile defines HAVE_STDINT_H.
Note that unfortunately sys/types.h often tries to provide types now in
stdint.h. We do the same collision-avoidance we do with our shorthand
types, but this could clobber correct definitions for the explicitly-
sized types on systems without stdint.h. (The only mainstream platform
not shipping stdint.h is MSVC, and we provide specific typedefs for that
platform.)
Some systems also provide a sys/inttypes.h with the same definitions. We
ignore this.

DETAILS :
The important change is setting pfont->font_name for CID fonts.
Before now it contained empty string. Other changes are minor
and only provide a data transfer.
file_name_combine : Improve the choice of the default GenericResourceDir.
DETAILS:
This patch does not change any behavior with a regular build.
The default value for GenericResourceDir can be configured
with -sGenericResourceDir=path . If not specified, it
chooses the first directory in LIBPATH, except (.),
and combines it with ../Resource .
The default value for FontResourceDir can be configured
with -sFontResourceDir=path . If not specified, it
chooses the first directory in LIBPATH, except (.),
and combines it with ../Resource/Font .
findresource was buggy : it returned a path with GenericResourceDir
when the real resource file is in another directory.
Now it first searches in LIBPATH, and if not found calls ResourceFileName .
We can't ever call ResourceFileName from findresource,
because it ever retrieves a single path. See the bug above.
Therefore with multiple resource directories it is conforming to PLRM
but differs from CPSI.

Fix (pdfwrite) : When advance width has non-zero y component, the width was set to zero.
Bug 686764 "Overlapping characters".
DETAILS :
The test document embeds a font, in which some characters
have a small non-zero y component of the advance width.
It looks as a buggy font. The pdfwrite writes zero to Widths array
(that's correct, because it is only useful with zero y component),
and did not generate glyph positioning commands (the bug).
This patch makes pdfwrite to be tolerant to such buggy fonts
with generating glyph position for subsequent glyph.

Fix (pdfwrite) : Unwinding a part of the previous patch
and improve the OS/2 table writing ann embedded CIDFontType2.
Bugzilla Bug 686759 "pdf to pdf doesnt work".
DETAILS :
The previous patch appears wrong and caused a regression
due to the change to "have_cmap = no_generate && !writing_cid,"
in gdevpsft.c . This patch unwinds it. Also the log message
of the previous patch is fully wrong. The CID font in the test document
for 686759 does not contain cmap and the cmap must not
be written. But with the previous patch a corrupt cmap
was written. Accessing the wrong font copy pdfwrite
failed to compute glyph widths and therefore converted the font
into a bitmap font. This patch restores the code
to "have_cmap = no_generate,". The bug 686759 is reopened.
Also we detected that the OS/2 table was written
wrongly in some circumstances : its position in font
file did not correspond to one specified in the font
header. This patch fixes it.

The code was making an assumption about the internals of the opaque

linux and macos, so the compile of course fails.
This commit temporarily breaks diff.bmp output on win32, which allegedly
cannot fseek() beyond the written end of the file so the row-reversal
logic will fail. This will be corrected in another revision.

Add pngalpha device that uses RGBA, with the alpha channel
providing pixel coverage. Used for generating PNG images with a
transparent background.
DETAILS
Add missing initialiser for get_clipping_box to
prn_color_params_procs macro. (src/gdevprn.h)
Avoid cast warning for software_key (src/gdevpng.c).
Add pngalpha device that uses RGBA. This requires custom
encode_color and decode_color procedures to put RGB in the
first three bytes while leaving the fourth A byte as opaque.
To avoid gx_no_color_value, the alpha is stored inverted so
opaque is 0x00 and transparent is 0xff.
If pngalpha is told to fill the entire page with white, it uses
the kludge of instead filling with almost white and transparent
(0xfefefeff). This works because it is triggered by "erasepage",
but not by "1 setgray clippath fill". A custom open_device and
put_params are needed to save the clist or memory device
fill_rectangle, and to restore the pngalpha_fill_rectangle.
A custom copy_alpha is required to correctly blend RGBA. The
blend is based on pixel coverage, not true transparency
Ghostscript doesn't pass transparency to the device. Alpha blend
maths from Porter and Duff 1984 paper for "A over B". RGB values
are stored without pre-multiplication. A custom
pngalpha_create_buf_device is used to replace the memory device
implementation gx_default_copy_alpha with pngalpha_copy_alpha,
but not to replace clist_copy_alpha.
The pngalpha device is successful at giving a transparent
background to many images such as colorcir.ps and golfer.eps,
but not tiger.eps which fills the clipping path with grey.
It does not implement a transparent background for PDF 1.4

Bug #686753 "Wrong Display of Multiple Master Fonts".
DETAILS:
The test document creates a Type 3 font, in which BuildChar
procedure defines a copy of MM font and later replaces
WeightVector in it.
A new PS operator introduced to handle it.
Adobe implementations do so.
We are not happy with the change of VM with no regard to 'restore'.
It appears compatible with the test document,
because it calls setweightvector before rendering each glyph.
(Another interesting point is that the test document executes
"0 setcachelimit" before rendering a glyph).
But it is not compatible to CPSI (a special test done).
Providing a correct restore appears too complicated -
need to change the data representation to 'ref'.
Delaying it until it is really needed.
Alternatively we could obtain a fresh copy of WeightVector
in each call to *show, but it would be a significant performance flaw.
The patch fixes the problem explained in the bug report #686753,
but the supplied document has another problem :
with pdfwrite some characters are converted to raster.
To be fixed separately.

file_name_combine : (1) Implement the extended search method in resourceforall,
resourcestatus, ResourceFileName. (2) Don't check permissions for command line argument files.
DETAILS:
This patch does not change any behavior with a regular build.
To skip the permission check with argument files we added a flag into
gs_context_state. This is only a secure way to pass the information
across PS interpreter, which executes .runfile with any argument file.
Per Adobe specification, a resource category can define the ResourceFileName procedure,
which generates a resource file name from resource instance name.
Since Ghostscript uses an extended search method for finding resource files,
the strong Adobe's semantics appears inapplicable.
Ghostscript implements an extended semantics.
Finding a resource file while executing findresource or resourcestatus,
Ghostscript does not call ResourceFileName. Instead that, it searches directories
with an extended method explained in How Ghostscript finds files.
ResourceFileName may be called from a Postscript program such as a resource installer.
The default implementation for ResourceFileName first checks whether
GenericResourceDir specifies an absolute path. If so, ResourceFileName uses its value
to generate the result. Otherwise, it tries to find an existing resource file with
the extended method. If it succeeds, ResourceFileName returns the path
to the resource file found. Otherwise it uses GenericResourceDir to combine a default path.
Note that with a single resource directory and an absolute ResourceFileName the behavior
appears equivalent to Adobe's one.
The new search method doesn't distinguish 'lib' and 'Resource' directories.

Fix for #686755 sgirgb device. The sgirgb device would produce compiler
errors if included in version 8.00 or later.
DETAILS:
The sgirgb device had not been modified to match the changes made in the
device API with version 8.00. These were fixed. In addition a couple of
compiler warnings were removed. AN unsed variable (sptr) was also
removed.
Note: I am unable to test this fix since I do not have an sgi system.
The inclusion of the sgirgb device also creates link errors in a WinXP
build due to undefined/missing bzero. Since this was not changed, I
am assuming that this is not a problem on an sgi system.

file_name_combine : Implementing new command line arguments:
-sGenericResourceDir= and -sFontResourceDir= .
DETAILS:
This patch does not change any behavior with a regular build.
With NEW_COMBINE_PATH 1 the new arguments replace
default values for GenericResourceDir and FontResourceDir .
A consistency check is added to gs_res.ps .
It signals an error if the value of GenericResourceDir
is inconsistent with LIBPATH. An automatic insertion of it
into LIBPATH appears cumbersome because the access to LIBPATH in C code
goes through gs_main_instance_s.
The operator .file_name_combine changed the prototype.
A boolean result is added instead a failure on error.
This simplifies error processing in PS code, especially
because the 'stopped' changes the memory allocation mode.

file_name_combine : Adding the 'no_neighbour' argument.
DETAILS:
This patch does not change any behavior with a regular build.
It slightly change behavior when built with NEW_COMBINE_PATH 1.
The 'no_neighbour' is a boolean, which protects steps from
a directory to its neighbor directory in file_name_combine.
With true argument the combination
(x/y) + (../z/t) fails
but
(x/y) + (../y/t) succeeds.
With false argument both combinations succeed.
The argument is added to both C function and PS operator.
We apply false argument while executing .libfile
and while generating PermitFileReading.
True argument is used in FAPI support to locate
FAPI-handled font files (which generally are not PS files,
and they are not being read with PS operators).
With NEW_COMBINE_PATH 1, THIS IS INCOMPATIBLE CHANGE.
To access resources, run Ghostscript with specifying
a resource directory in the -I command line argument.

Initial commit for the new SAFER logics.
DETAILS:
This patch should not change any behavior unless
NEW_COMBINE_PATH is changed to 1. With 0 a minor meanful
change is the replacing .pathstring_not_bare with .file_name_combine
in gs_fapi.ps (which fixes a bug in FAPI support,
and doesn't affect builds with no FAPI).
The change is compatible unless NEW_COMBINE_PATH is 1.
Incompatibility issues with 1 are explained below.
With NEW_COMBINE_PATH 1 the patch defines a new logic for
.libfile, SAFER, and related things :
1. Default values for GenericResourceDir and FontResourceDir
are platform dependent.
(The old code always use Unix notation - a bug).
2. Default value for GenericResourcePathSep is platform dependent.
The value is used before non-directory items only.
(The old code always use Unix notation - a bug).
(The old code used the value before directory items - a bug on OpenVMS).
3. PLRM specifies GenericResourceDir to be a single absolute path name.
But Ghostscript's tradition is to load library files
form a list of directories. Since we want to propagate
this tradition to resource files, we get a conflict.
To resolve the conflict, we allow GenericResourceDir
to be a relative path, which is being concatenated with
LIBPATH items. Thus we provide an extension of Postscript.
4. When a LIBPATH item is being concatenated with GenericResourceDir,
an abnormal behavior appears when GenericResourceDir references parent.
Exactly, concatenating the (.) item of LIBPATH with
the default GenericResourceDir, which is (../Resource/),
we get (../Resource/), i.e. it searches in a directory,
which users don't expect to. We work around the abnormal
behavior with skipping such paths while executing .libfile .
More precisely, the .libpath algorithm is :
For each LIBPATH item :
- combine it with the argument string;
- if the (reduced) combination refers the parent, skip it;
- otherwise try to open the path. If succeeded, exit with it.
If no success, fail with undefinedfilename or invalidfileaccess.
Here and below we used Unix notation just for simplifying
the log message. All statements to be generalized for any platform,
and they are true for any supported platform.
5. A consequence of our workaround for (4) is a new constraint to .libfile :
Let x is a cwd.
Let x/../y exists. Lets mark it as y1.
Let LIBPATH contains cwd and a directory z, which is not cwd.
Let z/../y exists. Lets mark it as y2.
Consequently y1 != y2.
Executing
(../y/f) .libpath
searches y2/f, but does not search y1/f .
The old code searched both in non-safer mode.
THIS IS INCOMPATIBLE CHANGE.
6. A better workaround for (4) would be an implementation
of RESPATH, which by default generates from LIBPATH
with replacing (../Resource/) with (./Resource/).
This requires to maintain a new directory lists.
.libfile should get an additional argument,
which specifies a search list - LIBPATH, RESPATH or FONTPATH.
We do not make this improvement now,
but will add it to Issues.htm .
7. If a path starts with a number of parent references,
a template with same number of parent references
must be added to permission list to allow the access.
The template (*) allows access to any file.
THIS IS INCOMPATIBLE CHANGE, because
the old code ever rejects parents.
8. GenericResourceDir and FontResourceDir are not being added
to permission list while .locksafe. Instead that,
we combine them with all LIBPATH items,
and add the combinations to the permission list
unless it references parent.
THIS IS INCOMPATIBLE CHANGE, but for non-exotic cases
(such as "(../Resource/CMap/H) .libfile" in a document)
it should be equivalent to the old behavior.
9. Scratch files with a non-absolute prefix always open
in a scratch directory. The old code can open them
in current and parent directories if an user modified
a default prefix in C code.
THIS IS INCOMPATIBLE CHANGE for users who had modified
a scratch file prefix in C code.
Permission for scratch directory is not checked
as well as in old code.
A. The operator .filenamedirseparator is removed,
because it cannot work properly on OpenVMS.
On OpenVMS it needs both prefix and trailer to
determine a correct separator.
We removed it because the new logics never needs it.
B. The operator .pathstring_not_bare is removed,
because .file_name_combine performs it's job better.
C. The functions gp_pathstring_not_bare, gp_file_name_references_parent,
char *gp_file_name_concat_string are not longer in use.
D. New operators added to maintain the new logics :
.file_name_combine
Combine a file name with a prefix.
The first argument is a prefix, the second is a file name.
Internal syntax of arguments and result is platform dependent.
The combination is being reduced to a shortest equivalent,
but if it starts with cwd reference, the starting
cwd reference persists.
- .file_name_separator
Returns a readonly string, which represents a separator
which is used in file names between directory item and file item.
Used for making the default value of GenericResourcePathSep.
- .file_name_directory_separator
Returns a readonly string, which represents a separator
which is used in file names between two directory items.
Used for making the default value of GenericResourceDir.
- .file_name_parent
Returns a readonly string, which represents a parent reference.
Used for making the default value of GenericResourceDir
and GenericResourceDir.
.file_name_parents
Returns an integer equal to the length of maximal
anchor substring, which includes parent references and separators only.
Used in generating the permission list from LIBPATH and
[GenericResourceDir FontResourceDir] as a workaround
for (6).
We believe that all them are necessary, except the last one,
which is temporary used in (8) as a workaround for (6).

gp_file_name_combine : Adding more helpers for OpenVMS support.
DETAILS:
The previous patch unintentionally set NEW_COMBINE_PATH=1.
This one repairs it.
OpenVMS uses different separators for directory and file
items - '.' and ']'. More helpers added to resolve this.
gp_file_name_conbine_generic now checks which one is needed
for concatenating paths.
gp_file_name_combine : Implementing some useful functions.
DETAILS:
This patch doesn't change any behavior.
The new functions will be used with NEW_COMBINE_PATH=1.
Probably we don't need gp_file_name_reduce, but it's implementation
is pretty nice and isn't obvious.
gp_file_name_is_absolute will replace gp_pathstring_not_bare.
NEW_COMBINE_PATH=1 wan't need a special check for cwd.
gp_file_name_is_from_parent will replace gp_file_name_references_parent.
The new function only check partent at the beginning of the path,
and should be used with reduced paths only.
We could code an in-place reduction with :
gp_file_name_combine_result
gp_file_name_reduce_inplace(char *buffer, uint *blen)
{
return gp_file_name_reduce(buffer, *blen, buffer, blen);
}
but we believe that
1. Aliasing const with non-const isn't a valid C.
Rather GS contains multiple const hacks, we don't want to add another one.
2. The input buffer must have space for the trailing zero,
which is not accounted in *blen.
The patch also includes a minor cleanup of comments and gp_file_name_combine_generic.

Implementing gp_file_name_combine.
DETAILS :
This patch introduces a new code, which is currently
disabled with "#define NEW_COMBINE_PATH 0" in gp.h .
The new function gp_file_name_combine concatenates
two paths and then reduce the concatenation with excluding
parent references when possible. It is platform dependent,
but we could factor out a big common part - see gp_file_name_combine_generic.
Platforms define 8 small helpers for it.
The gp_file_name_combine and its helpers were debugged on Windows
with emulating other platforms. A help wanted to
test them on real platforms. For testing them
replace 0 with 1 in the definition of NEW_COMBINE_PATH
in gp.h and rebuild.
We do not protect definitions of new functions with
NEW_COMBINE_PATH switch, because we want them to be syntax-checked.
Some old functions, such as gp_pathstring_not_bare,
gp_file_name_concat_string will be reconsidered later,
because the helpers perform similar work in a generalized way.
Probably some of old ones to be removed. Our strong intention is
to remove gp_pathstring_not_bare, because it's behavior looks
strange from the user's end.
Reorganizing lib_open, lib_file_open, lib_file_fopen, file_open_stream functions
to allow to check permissions with a combined file name.
DETAILS :
This should be an equivalent change.
It is a preparation for implementing static resources.
This patch moves the directory enumeration cycle from lib_file_fopen
to lib_file_open. After that we have a place in lib_file_open
in which both combined path and permissions are accessible
(more precisely, this place is in lib_fopen_with_libpath).
The checking permissions in there will be next improvement.
This patch defines a stub for gp_file_name_combine function.
Temporary it is placed into zfile.c .
Later it will be moved to platform dependent modules.

Support for JBIG2 streams with a JBIG2Globals shared data reference.
DETAILS:
The JBIG2Decode filter can take an optional /JBIG2Globals parameter,
always an indirect object reference to another stream. This commit adds
a new .jbig2makeglobalctx operator that takes a bytestring contanting
the global stream data, runs it through the decoder library and wraps
the resulting context pointer in an astruct which is returned as a
special -jbig2globalctx- object on the postscript stack.
A new procedure called from inside applyfilters in the pdf decoder takes
care of spooling the global data into the bytestring and installing the
astruct under the .jbig2globalctx key in the parameter dictionary. The
filter implementation looks for this and passes it to the page decoder
instance if it's available. The original JBIG2Globals key is ignored by
the actual decode filter implementation.
Fix (pdfwrite) : -dSubsetFonts=false did not work with incremental fonts.
DETAILS :
pdfwrite created a "complete" copy of a font at the first appearance of the font.
With incremental fonts it missed incremental glyphs with -dSubsetFonts=false.
The patch checks whether a glyph is added incrementally and
replaces the "complete" font copy with a font subset.
Bug #686735 "-dSubsetFonts=false produces a bad PDF".
The core of the patch is the change to gdevpdte.c .
Other changes just pass a necessary data through internal interfaces.
This patch should not change behavior with -dSubsetFonts=false,
which is used by default for the regression testing.

Fixing the device finalization problem.
DETAILS :
pdfwrite (and possibly other devices) perform a huge work within close_device.
Since close_device is called via finalization method from memory
manager, some device structures could be released before calling
device_close, so that the huge work could not safely complete.
Also it could return error codes, which were entirely lost.
This patch calls gs_closedevice implicitly when a device
is about to uninstall. We catch 2 such events : when the interpreter
is about to exit, and when the interpreter executes setdevice.
This should be enough for "external" devices, such as printer drivers.
Internal devices do not receive these calls.
Note that a call to gx_device_fill_in_procs is added after assign_dev_procs
from gx_default_create_buf_device. Not sure why it was not done before.
After assign_dev_procs, ppmraw had ununitialized procs.
Also note that is_open flag is now unconditionally resets in gs_closedevice.
The new code needs to reset it to prevent redundant call to close_device from
device finalization method. The redundant call causes
a crash if pdfwrite has insufficient disk space to store the
output file (debugged with dina3_watermark.pdf) .

This is initial commit for implementing static resources.
DETAILS :
1. Adding a new iodevice %static% with the new file ziodevst.c .
It is used for opening files placed in static data segment.
They need to be accessed as PS files due to multiple reasons,
including the implementation of gs_ciddc.ps and for PS procedure
ResourceFileName defined in PLRM.
2. Implementing a queue for delayed invocation
of initialization functions at end of gs_init.
This feature is necessary due to customized
builds of Ghostscript : some 'dev' depend each
on other and some functions are needed to execute
after all devs are preset. Currently it is only used
for obtaining the Unicode Decoding resource,
but later it will be used for perfectly consistent
processing of font and CID font map files,
both with FAPI and without it.
3. gs_resmp.ps slightly changed for handling
resource maps which are not defined as files.
4. The new file gs_resst.ps implements a procset
for handling static resource files. Both gs_resst.ps and
gs_ciddc.ps use the %static% iodevice.
5. The new file gs_resst.ps creates a map of resource files
placed in static segment. Later it would be nice
to generate it during GS installation. With the defined
resource set gs_init.obj grows up to 1.5Meg,
but both MSVC and gcc/Cygwin could handle it.
Currently all resources in gs_stres.ps are COMMENTED OUT
to prevent problems building Ghostscript with COMILE_INITS=1
on Mac and VMS. To uncomment them, replace '%-' with empty string.
This patch was locally tested with entire comparefiles
with COMPILE_INITS=0. It should not cause regressions.
Also it was slightly tested with COMPILE_INITS=1 :
the static resources work fine.
The patch assumes that during a GS build resource files
are placed in gs/Resource/ . It uses 1 Decoding and
a dozen of CMaps, which are necessary for the CID font emulation
and for FAPI to work. You need to uncomment them
in gs_stres.ps .
When GS is invoked, resources are being loaded from both
the static segment and from the OLD(!!!!!) default path.
In other words, the resource machinery works fine,
but the default resource path is not fixed yet.
I intend to fix it in the next day or two.
The patch depends on
http://www.ghostscript.com/pipermail/gs-cvs/2003-February/002950.html
The patch does not include CMaps and Decodings resources.
They to be added separately.
Enhancing the functionality of geninit.c .
DETAILS :
1. Implemented "long" relative paths. See translate_path.
Not sure what to do with separators on Mac.
See the __MACOS__ section.
This change was not debugged on Mac.
In case of problems please patch it.
2. Moved some error messages to prefix_open,
to allow translated paths to be displayed.
3. Implemented an intact including of files.

Fix : Improving the CIDFontType 2 font copying.
DETAILS :
I believe that the code about copying CIDFontType 2 glyphs
is overcomplicated with mixing CIDs and GIDs, and needs to be
cleaned up. The old code had an obvious inconsistency :
it allocated a smaller array for glyph indices than written,
causing a heap damage. This patch simply makes the code to be
self-consistent. I can't say that I completely
understand whether CIDs/GIDs passed correctly or not.
Now it is working, but the correctness was not proved,
and Acrobat Reader doesn't show the glyph with /CIDTTEMUL
(see below).
The problem was detected with COMPILE_INITS=1 with emulating
a CID wont with mshei.ttf . The following program had crashed
with pdfwrite :
/glyph 2300 def
/ShinGo-Bold /CIDFont findresource
100 scalefont setfont
100 200 moveto glyph glyphshow
/CIDTTEMUL /CIDFont findresource
100 scalefont setfont
100 100 moveto glyph glyphshow
showpage
with the cidfmap file like this :
/ShinGo-Bold << /FileType /TrueType /Path (f:/WIN2000/Fonts/batang.ttf) /SubfontID 0 /CSI [(Japan1) 2] >> ;
/CIDTTEMUL << /FileType /TrueType /Path (f:/WIN2000/Fonts/mshei.ttf) /SubfontID 0 /CSI [(Japan1) 2] >> ;
The effect is indeterministic.
When I build GS with regenerate gs_init.c,
it crashed if run in same session of Developer Studio.
But if I close-open the Developer Studio and run GS,
it doesn't crash.
The patch should enlarge the array, which was written outside
the index range. The problem looks gone.
Meanwhile the CID/GID logics in gxcopy.c to be revised someday.

Partial fix for 684340. Remove the macro gx_color_device_must_halftone
and its one (incorrect use).
DETAILS:
The macro gx_color_device_was meant for situations in which the device
was known to be a color device and it was needed to know if halftoning
was required. With the 8.00 changes in the graphics library, the
one situation that it was being used is incorrect. The macro was also
wrong since it was checking dev->color_info.max_gray. It should have
been checking color_info.max_color. The macro was removed. Please
use gx_device_must_halftone in its place.

pdfwrite : Account GlyphNames2Unicode while creating ToUnicode CMaps for simple fonts.
DETAILS:
This patch improves the previous one.
It generalizes the GlyphNames2Unicode processing for any simple font.
GlyphNames2Unicode is an undocumented facility, which Adobe Postscript
printer driver PScript5.dll Version 5.2 uses to communicate with
Adobe Distiller. Adobe applies it to Type 3 and Type 42 fonts.
Adobe uses Type 3 with GlyphNames2Unicode only for compatibility
with interpreters, which cannot handle Type 32. With other
interpreters (including Ghostscript) the generated PS program
skips GlyphNames2Unicode data. Therefore the feature
is now implemented for Type 3 but it is not involved while
processing such documents. Need to patch "32 /FontType findresource"
to involve it. Probably with pdfwrite the DSC parser should recognize
the creator and exclude 32 from /FontType resource category.
This patch unwinds the enhanced functionality of gs_font_procs::glyph_info
with GLYPH_INFO_UTC16, which was done with the previous patch,
and introduces a new virtual function gs_font_procs::decode_glyph.
Doing so because GLYPH_INFO_UTC16 causes multiple redundant code
for various font types due to dependence on interpreter structures.
SF bug #684120 tracks additional issues.
Initial implementation of the /JBIG2Decode filter. This adds a '$(PSD)jbig2.dev'
FEATURE_DEV which links in the libjbig2dec decoder library. This version does
not support the optional /JBIG2GLOBALS parameter for sharing information between
page images. However, it is still useful as this parameter has been empty in
the files we've seen. The feature in enabled for the autoconf build if the
decoder library is found on the system, and remains optional with the other builds.
pdfwrite : Account GlyphNames2Unicode while creating ToUnicode CMaps
for Type 42 fonts.
DETAILS:
GlyphNames2Unicode is an undocumented facility, which Adobe Postscript
printer driver PScript5.dll Version 5.2 uses to communicate with
Adobe Distiller. Adobe applies it to Type 3 and Type 42 fonts.
Type 3 with GlyphNames2Unicode is used only for compatibility
with interpreters, which cannot handle Type 32.
Since Ghostscript is not such, there is no need to implement
Type 3 with GlyphNames2Unicode. We don't do that.
This patch enhances the functionality of gs_font_procs::glyph_info
with retrieving Unicode UTC-16 code for a glyph. This enhancement
is implemented for practically useful cases only, which are
restricted with Type 42.
The gs_font_dir::glyph_to_unicode
callback is now removed because it is not longer useful.
SF bug #684120 tracks additional issues.
Working on this patch, I tried put the Unicode Decoding table
as a default value to FontInfo.GlyphNames2Unicode and remove the unicode_decoder.
But it appears not working, because test.ps for SF bug #529103 needs to
collect substitutions from both FontInfo.GlyphNames2Unicode and Unicode Decoding.
I removed the "WARNING: /Unicode /Decoding resource in not accessible",
because the flag for preventing its repetitions is not accessible from
gs_font_procs::glyph_info. A similar warning in lib/gs_pdfwr.ps still works.
The display device (src/gdevdsp.c) was displaying pure magenta as
white when using the DISPLAY_UNUSED_LAST mode.
DETAILS:
The cause of the problem was a sign bit extention in a 32 to 64
bit conversion (long to gx_color_index). The fix was to add casts
to force the conversion to gx_color_index (which is unsigned) earlier
in the assigment.

pdfwrite : Generating ToUnicode CMaps for simple fonts.
For fonts with random encoding it allows to Copy-Paste text
from viewers and to search a text.
DETAILS:
This code requires /Unicode /Decoding resource.
If the resource is absent, PDF will be written without ToUnicode CMap,
a warning is written to stdout explaining that the resource may be useful,
and another warning may be written to stderr if the resource is actually
useful for the document.
To access the resource I introduced a special operator .setupUnicodeDecoder .
It is called from gs_pdfwr.ps and stores the resource to gs_font_dir,
together with a callback which performs the decoding.
This is only a way to pass the resource through the graphics library.
It is definitely not a device parameter, and converting it to
C structures would be hard.
I don't like the big stuff added into zfont.c, but I haven't got
a better idea where to put it.
Minor change : fixed Cygwin/gcc compiler warnings.

The CID to TT mapping : Building CIDMap with SubstNWP.
DETAILS:
This patch should not change any behavior if a new file
gs/lib/cidttmap is not added. Normally it is not.
With this patch narrow, wide and proportional Romans
may substitute each another while emulating a CJK CID font
with True Type font. Usually True Types contain insufficient
glyph to render all them. The substitution prevents missed glyphs.
This patch introduces a new special operator .fillCIDMap .
It composes a CID map from a Decoding, a True Type cmap,
and SubstNWP. PS code would be too big and slow for this purpose.
The implementation of the CID font emulator is almost complete except 2 features :
1. The CID font to CID font mapper and
the True Type to CID font mapper use different map files -

The CID to TT mapping :
1. Providing an access to glyphs on demand.
2. Handle TTC font format.
DETAILS:
This patch should not change any behavior if a new file
gs/lib/cidttmap is not added. Normally it is not.
With this patch glyf and loca tables are being skipped while loading
a True Type into RAM. An access by demand is provided instead
(This works for CIDFontType 2; it is not used for Type 42).
Map file may contain records with SubfontID, which
specifies a font number in a TTC collection.
TTC format is implemented for disk files only,
because embedded fonts never use it.
To provide the on-demand access, the patch introduces a special
extension of the Postscript language.
A CIDFontType 2 dictionary may contain /File with a file value.
It should be a positionable file of the TTF or TTC format.
When it presents, the dictionary must contain /file_table_pos,
which's value is a dictionary of 2-element arrays, which specify
position and length of a TT table in the file. 2 arrays
must present with keys /loca and /glyph.
We would like to optimize this implementation.
See comment in gs_type42_get_outline_from_TT_file.
Fix for 673108. The test file has a stream which contains an invalid
stream length. However Acrobat handles the file.
Details:
The invalid stream length was bad enough that we were positioning beyond
the end of the file when we searched for the endstream. A check was
added for this case and if so then we ignore repositioning the file
before searching for the endstream. Note: There is already logic in
the code which emits a warning message if the endstream is not found.
A second part of this fix was to clean up the stack if the endstream
is not found.

CID font emulation : Adding a code for CIDMap generation,
and moving the xlatmap scanner to gs_fntem.ps .
DETAILS:
This patch only changes a code which work for
FAPI or for CID font emulation. Regular GS invocation
should not change a behavior.
This is a next step of the CID font emulation.
Now it correctly maps most CIDs to Unicode fonts.
Secondary changes :
- I made xlatmap accessible from gs_ttf.c .
It should be used choosing a cmap.
- improving some comments and function names.
- Removed a redundant definition of a CIDFont,
which was unintentionally introduced with the previous patch.
The implementation of the CID font emulator is still incomplete :
1. Entire True Type fonts are loaded into VM.
2. SubfontID is being ignored.
3. The CID font to CID font mapper and
the True Type to CID font mapper use different map files -
cidfmap and cidttmap.
4. Access to glyphs by demand is not done.
5. SubstNWP is being ignored.
6. The choice the Unicode cmap is hardcoded.
Should use xlatmap instead.
The previous log message recommends to use PMINGLIU.TTF.
Actually it requires a True Type bytecode interpreter,
which GS doesn't provide. The font mshei.ttf does not.
Fix for incorrect colors with pswrite device when painting rectangles.
SF bug 677009.
DETAILS:
The call to gdev_vector_update_clip_path followed the update_fill call

which reverted to whatever color was part of the previous saved gstate.
Changing the order of the calls fixes the problem.

Enhancing the resource machinery with mapping CID fonts to True Types.
DETAILS:
This patch should not change any behavior if a new file
gs/lib/cidttmap is not added. Normally it is not.
Adding 2 new files gs_fntem.ps and gs_cidtt.ps and reorganizing
old files gs_cidfn.ps, gs_fapi.ps, gs_resmp.ps with them.
This moves a part of FAPI support to a more general level.
The moved stuff is shared with the FAPI and the new CID font mapper.
After this change Ghostscript can load Unicode True Type fonts
as a substitution to a CIDFontType 2 and render it.
At least the Windows font PMINGLIU.TTF succeeds.
But the implementation is very incomplete :
1. The CID to GID mapping is fully wrong.
2. Entire True Type fonts are loaded into VM.
3. The CID font to CID font mapper and
the True Type to CID font mapper use different map files -
cidfmap and cidttmap.
All these 3 solutions are temporary and to be improved later.
To involve the new feature, create a new file gs/lib/cidttmap,
and put records to there of the following format :
/ShinGo-Bold << /FileType /TrueType /Path (F:/WIN2000/Fonts/PMINGLIU.TTF) /CSI [(Japan1) 2] /SubstNWP /Japan1 >> ;
It is similar to gs/lib/FAPIcidfmap, see Use.htm about the latter.
This patch does not include a change to documentation,
because it is too early to announce it to users.
FAPI : A further improvement for the GS/FreeType bridge.
Patch from Graham Asher.

- removed unuseful dependencies from makefile.
Fix : Eliminate .forceput from gs_resmp.ps .
DETAILS:
This patch should not change any behavior.
A mapped category used an array to store a set of procedures.
Sometimes the set grows, and the old implementation
used .forceput to replace the array with a bigger one
in the category dictionary, which is read-only.
The new code represents the set as a dictionary,
so that .forceput is not longer needed.

fix for #667658 when CR and/or LF comes between the '~' and the '>'.
DETAILS:
The logic was also fixed so that if the end of buffer is reached while
searching for the '>' character (past CR and/or LF) no error would be
issued unless we have the 'last' condition indicating that no more data
is available.
Thanks to Igor M. for spotting the above potential problem during code

Fix : Removing an unused variable from set_cache_device.
[src/gxchar.c]
2003-01-26T08:24:31.000000Z Igor Melichev
Implementing a new user parameter AlignToPixels and
a new command line argument AlignToPixels.
They allow to choose the alignment of glyphs to
integral pixels or to subpixels while a text rendering.
DETAILS:
This patch should not change any behavior except
-dAlignToPixels=0 is specified.
A change to documentation about the new parameter is included.
With NEW_TYPE1_HINTER = 1 the value 0 of AlignToPixels implies :
1. Caching a glyph raster, fractional glyph origins
give different images, which are stored
in individual slots. The space consumption in the
character cache increases. This happens for all font types.
2. While hinting a Type 1 or 2 font, glyph origins and widths
are rounded to subpixels rather than to pixels, and the grid fitting
is done to the subpixel grid.
CIDFontType 0 descendents had NULL pointer to gs_font_dir.
The new code needs to access the font directory,
so the pointer is now set.
The new code needs glyph origin and log2_scale to lookup
a glyph in cache. Therefore show_proceed and
set_cache_device were reorganized with a new function
compute_glyph_raster_params. The new algorithm uses a
slightly different (and more complicated) logics
for computation and initialization of penum->origin.
It was well tested, but in case of problems please
consider it as a weak point.
Universally prefer the __MACOS__ platform predefined symbol used by recent
releases of Metrowerks CodeWarrior to the older __MACINTOSH__.

New Type 1 hinter : (1) It did not work with pdfwrite because
gx_path_init_bbox_accumulator doesn't provide a memory.
(2) Coded an alignment to subpixels.
(3) Removed a hack about suppressing a microscopic segment.
DETAILS:
This patch changes a disabled code only.
It codes an alignment to subpixels, but for a while
it is permanently turned off.
gx_path_init_bbox_accumulator is used by gs_default_glyph_info for
computing a bounding box for a glyph. It does not
store segments to memory, therefore a reference to memory manager
is not provided. But the new hinter accesses it
if a stack-allocated array overflows.
Implementing an immediate transfer of outline poles to
the output path without storing them intermediately in arrays.
This mode works when a grid fitting is not required.
Only exception is flex poles : up to 9 of them
are stored in arrays while flex accumulates.
It must not overflow arrays.
The hack about microscopic segment was a rudiment of old code.
gs_op1_closepath was unintentionally called while
exporting an outline from the hinter. I believe that
the hack is incorrect and should not be applied.
Some outlines render differently.
I'm sorry for mixing 3 things in a single patch.
I've started the subpixel alignment, and
then occasionally discovered other problems.
It's hard to separate changes after they are done,
and I don't think that the separation is so important.

FAPI project : fixing a problem about preparation renderer's

DETAILS:
Without FAPI renderers this patch doesn't change any behavior.
The old code crashed with Free Type because it misinterpreted
gs_font_cid0_data as gs_type1_data. Improving the protocol for
font data preparation : the new code now tells to a renderer about
a top-level CID font, then about it's descendents (which are Type 1),
then again about the top level font. A new type FAPI_descendent_code
represents a type of request. See comments, which this patch adds to code.

Update DSC parser to current Ghostgum Software version.
Fixes SourceForge bug #657289, SEGV on Alpha in DSC parser.
DETAILS:
A %%Page line with mismatched parentheses around the page label
was ignored, but parser state was updated to scanning pages, not
setup section. This resulted in access to dsc->page[-1] which
is invalid and caused a SEGV on Alpha. The updated code now
checks that dsc->page_count is non-zero before accessing
dsc- >page[dsc->page_count-1]. It also makes a second attempt
at finding the page ordinal at the end of a line like:
%%Page: (label with closing parentheses 1
Other parser updates include support for DCS2 files (which is
not quite compliant with DSC), removing a few compiler warnings,
%%HiResBoundingBox, %%CropBox, %%PageCropBox, and being more
resilient to incorrect DSC.

Changes for the 8.00 release to allow reading of PDF files from

pdfwrite : Implementing widthshow and xshow for composite and CID fonts.
The old (default) implementation converted to raster fonts
and gave inaccurate glyph positions. The new implementation doesn't
convert fonts to raster except for Type 3.
DETAILS:
This also closes the Source Forge bug
"[ 663635 ] ps2pdf cannot tune spacing by xshow for CJK text".
and provides better glyph positions with ashow for WMode 1.
There are small changes to graphics library :
1. Added interface function gx_current_char, which retrieves
a code of current character from a gs_text_enum_t instance.
The function was factored out from an old code.
2. Provided a default metrics for CID fonts for WMode 1.
This is done pretty roughly, because the interface
function glyph_info cannot pass some necessary information (WMode).
Minor changes :
1. Removed the comment "We know that the Tw and Tc values are zero",
It was wrong a long time ago.
2. Inserted a comment about unimplemented DW2. An old code near the
comment depends on the fact that DW2 is not implemented.
This patch brings more access to gs_text_enum_t::fstack
around the defined interface functions.

Fix for [ 664473 ] 64bit color indexes break X driver.
This fix corrects some problems found with the X window
driver and 64 bit gx_color_indexes found by customer 1110.
DETAILS:
The problems were found on Sparc workstations running the
Solaris 8.0. The problem has not been reported on other
systems. However the fix is simple (and contributed by
customer 1110) and should work on all systems. The fix
is simply to use "long" for values passed to X windows
system routines. This is done via a combination of casts
or local variables depending upon the situation. The use
of "long" for gx_color_index was the default prior to the
8.0 release. The X windows device does not need the extra
size for color values.

Within the display device, correctly allocate the memory device
with the correct structure descriptor.
DETAILS:
The display device was allocating a memory device by taking a
memory device prototype from gdev_mem_device_for_bits and then
using gs_copydevice on it. This allocates the wrong size
because the prototype does not have a structure descriptor. The
correct way is to allocate it with gs_alloc_struct with
st_device_memory as an argument. This bug was found when using
the display device in GhostPCL, which was complaining on
shutdown about the unfreed structure descriptors left behind by
gs_copydevice.

Source Forge bug "[ 667362 ] /rangecheck in --.type42execchar--", Customer #411.
According to Type 42 specifications, the segmentation is not allowed.
Perhaps the test file has it. IMO it is easier to fix than to prove to the customer.
This slightly changes the interface function gs_type42_data::string_proc .

Modifies pick_cell_size to make a more accurate, and less round-off
error dependent, selection of screen cell size.
DETAILS
The prior code in pick_cell_size used an unusual metric for
measuring the "closeness of fit" of an actual screen cell to the
requested frequency and angle. If the angle variation was 0 (quite
likely for the common 0/45/90 degree angles), the frequency
variation was ignored. In addition, this metric was very sensitive
to floating-point arithmetic round-off errors. The new metric is
both more reasonable and less round-off error dependent.

Reducing the C stack consumption in ztype1execchar.
The new code must be equivalent to the old one.
DETAILS:
The new type 1 hinter (with NEW_TYPE1_HINTER = 1 in gx.h)
puts more 11K of data to C stack. Perhaps due to a recursion
in bbox_draw 2 instances of the hinter were placed in C stack
simultaneously, causing C stack overflow with gswin32c.exe on
Windows NT 4.0 (but not on Windows 2000).
Perhaps the recursion is not necessary.
Reorganizing the sequence of calls to avoid the recursion.
New argument 'exec_cont' was added to several

Corresponding comments are added in code.
Also z1_glyph_info prototype was added in ichar1.h .
It was missed a long time ago, Cygwin/gcc warned.
A further improvement may be done with factoring out
a common code from bbox_finish_fill, bbox_finish_stroke,
bbox_fill, bbox_stroke. Delaying it until a regression testing.
Allow tests to run without modifying the daily tracking database.
run_regression now takes the --track option to create and update daily
tracking databases, and runs normally otherwise.

issubclass(). This is required for Python 2.2 compatibility.

Include libz in the autoconf test for libpng.
DETAILS:
This is a fix for systems without interlibrary dependencies. We don't use
the LIBS variable constructed by default by the AC_CHECK_LIB macro and
did not maintain it in our previous zlib test, thus -lz was not included
on the link line in the libpng test.
Our primary test systems for the autoconf build (Debian GNU/Linux and MacOS X + fink)
include an interlibrary dependency, so this did not cause a problem. On
systems where this is not the case, it results in a confusing error.

This does not change actually behavior, because of the way M4 works,
the literal loop end was just interchanged with the implicit one from

went undetected.

Dropout prevention : (1) Replace the horizontal line processing.
(2) Returning the hack about horizontal lines for non-character fills.
This patch changes a disabled code only.
DETAILS:
With the old type 1 hinter, hinted outlines get
self-intersections at small resolution. It's a problem
of the old hinter. Perhaps it discovered a defect
in horizontal line handling.
With self-intersections, the side of spot interior
may be different for different parts of same line.
This patch completely replaces the handling of
horizontal lines. It maintains 2 lists of
horizontal lines, which correspond to y and y1
in fill_loop_by_trapezoids. Then we intersect those
lines with margins and add corresponding segments
of boundaries separately for each part delimited
with an intersection.
The
"* This is a hack to make sure that isolated horizontal
* lines get stroked."
was erroneously disabled for non-character fills,
causing a regression with QA_Inv.pdf .

Initial commit for a new type 1 hinter.
This patch must not change any behavior.
DETAILS:
This is a porting from HINTER branch.
The old hinter cannot handle overlapping hints,
but real fonts do use them.
The handling of overlapped hints cannot be done within
a single-pass algorithm. Therefore we intend to replace entire thing.
Besides, it should fix a set of known problems :
- stem degradation at small resolutions;
- stem missing or misrecognition;
- proper adjustment of dependent stems;
- suppress overshoots closer to Adobe;
This patch introduces a couple of new macros,
which will be removed later.

Reduce state.width delta radius calculation for shadings that was made too

DETAILS:
Previous commit mistakenly included the state.dr value as both the X and
Y component in the distance transform that produced the dev_dr vector.
The hypot is actually all that is required to handle getting the correct
scaled radius distance independent of the CTM rotation.
The use of state.dr for both X and Y preceded the use of hypot on dev_dr
and wasn't taken out when the hypot function use was added.

relatively to stem hint coordinates so that stems could not recognize.

Improving the dropout prevention algorithm
This patch changes disabled code only.
DETAILS:
In zchar42.c I set path adjustment to zero.
It is the correct value with dropout prevention.
The last revision of dropout prevention algorithm
appears buggy : the order of margins in margin_list
can be wrong and causes dropouts. This is essentially
important with CJK True Types, which have thing horizontal
stems and no hinting with GS.
This revision replaces the representation of margins
with a simpler one. It is not optimized for bold
characters, perhaps the optimization is not hard.
See comment in code about "bold".
A good advantage is the removal of insert_pseudo_margin.
It appears done due to insufficient knowledge of the old algorithm.

Improving and optimizing the dropout prevention algorithm
with splitting gx_default_fill_parallelogram into 2 variants.
DETAILS:
This patch almost changes a disabled code.
A simple reorganization of some enabled code should not
cause a behavior difference.
Filling a "small" character, we always subdivide trapezoids into
rectangles instead passing them to device virtual function.
It allows :
1. Not passing narrow trapezoids to applications
which implement fill_trapezoid with own means;
Narrow trapezoids could cause dropouts in there.
2. Optimize variants of fill_trapezoid algorithm which
are used for different purposes (preventing about 10% slowdown
with shadings).
We believe this change isn't harmful because
regularly we render small characters to cache device,
which simply forwards trapezoids to default implementation.
Alternatively we could insert a check for narrow trapezoids
into loop_fill_trap, but such check appears complex and
it would sensibly reduce performance.
New files added : gdevddrw.h, gxdtfill.h .
Change to lib.mak accounts them.
Besides that, with dropout prevention we now skip empty paths
in characters, because Adobe doesn't paint them.
Initial commit for the dropout prevention code in rasterizer.
It doesn't not change any behavior.
DETAILS:
Switching to new code is being controlled with DROPOUT_PREVENTION
macro defined in gx.h . Now it is set to "use old code".
This patch :
1. Ports the "margin" algorithm from HINTER branch.
Now the algorithm renamed to "pseudo-rasterization".
2. Ports the dropout prevention to gx_default_fill_trapezoid from HINTER branch,
providing a contiguous fill for slightly slanted trapezoids.
3. Adds CONNECT_RECTANGLES into gx_default_fill_trapezoid
providing a contiguous fill for highly slanted trapezoids.
4. Fixes some problems in the "pseudo-rasterization".
5. Disables all hacks about path adjustment and oversampling
when DROPOUT_PREVENTION is on. Those hacks were attempts
to fix dropouts for small characters, but they do not solve
the problem completely.
6. Provide visual trace instructions for debugging purpose.
Changes to gxpcopy.c and gxpflat.c only insert visual trace instructions for
debugging purpose. Currently all them compile to empty code.
Changes to gdevddrw.c, gxchar.c, gxtype1.c, gx.h
are protected with DROPOUT_PREVENTION. With current settings they
compile to old code.
Changes to gxfill.c are not so obvious. I was unhappy with duplicating
a thousand of lines in #if...#else...#endif. Therefore
I've inserted some dynamic checks. They are controlled with
'pseudo_rasterization' flag. Currently it always false,
so that inserted sections are either bypassed or immediately
return from subroutines.
Changes to lib.mak only add some dependences on vdtrace.h .
In local testing the patch caused no difference with
Comparefiles (if DROPOUT_PREVENTION is 0).
If someone wants to try new code, DROPOUT_PREVENTION to be modified in gx.h .
In this case all old hacks about path adjustment are disabled,
and therefore characters render some lighter.
Visual trace may be activated with -Tf option in gs command line.
Note that it paints a big draft for any character rendered,
so you should run only simple PS files with a single character.
Also the draft scale is hardcoded in VD_SCALE constants,
so it may give an unuseful result with big character rasters.
At last please remember that visual trace window is implemented
only for Windows - other platforms will not paint anything.
The visual trace window does not implement a regeneration of painting,
therefore windows must not overlap. Run gswin32.exe with no file,
move windows and then perform 'quit' to store window layout to system Registry.
here is a simple test, which visualize improvements when
DROPOUT_PREVENTION is on :

(/) show
showpage
With 72dpi the old code paints nothing.
The (DROPOUT_PREVENTION=1) paints a spot.
Testing the new code with -r300 001.01.ps, the box 001-12 renders better :
no dropouts in "4", characters look better.
In gx.h I've added FILL_TRAP_WITH_SWAPPED_AXES flag. The goal is to archive
and document a dead branch of the development. I'd like to store it into
archive and then remove it in the next revision.
Two temporary configuration switches added for benchmarking purpose :
- PSEUDO_RASTERIZATION in gxfill.c disables the pseudo-rasterization
separately from other changes.
- CONTIGUOUS_FILL disables additional checks in gdevddrw.c
separately from other changes.
With text documents performance change is almost invisible.
With Coons01.ps each of these flags give a 10% slowdown.
I guess the reason is that the code becomes too complex for
global optimization with MSVC 6.0 for Intel Pentium 3.
Other compilers/processors may give different results.

Prevent the bbox put_params from using the color mapping
functions before the device is opened.
Fixes Sourceforge bug #645531 "seg fault: bbox device + PAPERSIZE".
DETAILS:
Using "-sPAPERSIZE=a4 -sDEVICE=bbox" crashes in GS 8 when the
device parameters are being set prior to opening the bbox device.
bbox_put_params calls bbox_copy_params, gx_device_black
then the bbox encode_color which is NULL.
This is wrong because encode_color must not be called before
the device is open. See doc/Drivers.htm#Life_cycle for details.
Prior to the DeviceN changes this did not matter because
the map_rgb_color function was valid. Post DeviceN the
encode_color procedure is called and this is NULL until
just before the bbox device is opened.
The fix prevents bbox_copy_params from calling the
encode_color procedure while the device is closed.

Fix for [ 652147 ] overprintmode not boolean. Adobe TN5145 defines
the paramters to/from setoverprintmode/currentoverprintmode as being
boolean. This change modifies the implementation to match the TN.
DETAILS:
Previously the operators setoverprintmode and currentoverprintmode had
been defined to match the requirements of PDF which uses an integer for
the parameter. However Adobe TN5145 defines the postscript implementation
as using a boolean value. This change modifies the definition of these
operators in lib/gs_ll3.ps to convert the parameter type. The internal
operators .setoverprintmode/.curentoverprintmode still use the PDF integer
parameter. The postscript code in lib/gs_ll3.ps converts the parameter
type.

Handle TrueType fonts that contain poorly formatted 'post' tables.
These were seen as font subsets embedded in PDF files.
Fixes SourceForge bug #651164 for customer #150.
DETAILS:
The file contains an embedded TT font subset that has a badly formatted
'post' table. This table is used to replace names in the standard encoding
for specific glyphs. The 'post' table in question maps a bunch of glyphs
that are not part of the subset to the first name in glyphnames section,
but the glyphnames section is empty. It should have at least a single byte
of 0x00 to form a zero length Pascal string.
I also added a warning that prints if the DEBUG is enabled. Since the
'postglyphs' string is automatically extended with a 0x00 byte when the
problem is detected, the warning only prints once for the font.

Fix (FAPI) : Rename round() to fapi_round() to avoid shadowing the C99 call of the same name.
DETAILS:
In particular, the redeclaration of round() causes a compiler error under
Apple's gcc (October 2002 Developer Tools, MacOS X 10.2.2). MSVC doesn't
implement the C99 round() and in any case we don't need the full behaviour,
so a private implementation seems the best portable option.

Fixes SourceForge bug #646809 "/stackoverflow"
DETAILS:

causing /stackoverflow. Since the numbers are always sequential
the new procedure takes a range of numbers. The range is defined

placement may have left the impression that Format 3 still had the problem.
[lib/gs_cff.ps]
2002-12-04T19:50:47.000000Z Ray Johnston
Handling of OpenType (OTTO) fonts with CFF fonts inside would fail if the
CFF table was not the first table in the table directory. Also stack
overflow could occur when building the FDSelect array. Now Asian fonts
sold by Adobe (as OpenType .otf fonts) can be used with Ghostscript.
DETAILS:
The initial table scanning checked the 32-bit table type against the
(CFF ) string, but then failed to skip the following 12 bytes if the table
was not CFF. Since the initial table is usually BASE, most OTTO fonts were
not usable.
Also the FDSelect array construction used the stack, so could easily
overflow if there was a largest glyph index in the font was too large. The
method used creates a 65535 element array, then fills it using the info
from the font's FDSelect info. The extra elements of the array are 'trimmed'
using getinterval.

When adding a missing showpage to an EPS file,
don't bind showpage to allow user to override it.
DETAILS:
The EPS encapsulation code in ghostscript adds a showpage
if one is not present, so that displaying, printing and
converting all behave the same. Some users are feeding
multiple EPS files to ghostscript, intending to print them
on a single page. The current code will print each EPS file
on a single page. For example following code would print
three pages:
save
/showpage {} def
save (file1.eps) run restore
save (file2.eps) run restore
restore
showpage
With this fix, it will print a single page.
Other ways to avoid this problem are to use -dNOEPS,
or (file.eps) (r) file cvx exec

SourceForge bug "[ 624168 ] poor performance on patterns".
DETAILS:
Besides others, the document "a)page Afrique(VECTO).eps"
creates multiple redundant clip paths with any AI "pattern"
(actually it doesn't use PS patterns). The old code was
too conservative, using only a comparison of path identifiers.
The patch creates a stable copy of clipping path written to PDF,
and compares it when PS clip path changes. The old comparison
is left unchanged for better performance.
Also fixes return codes from pdf_put_clip_path and
improved the initializer of gx_device_pdf.

Fix for #609488 Problems in DeviceN test file. This resolves problems
that can occur if the transfer function are dependent upon the halftone.
(Which is true for the default hi res transfer function.) We were

in enumerating graphic state dictionaries via the 'forall' operator.

2002-11-05T00:10:37.000000Z Dan Coby
Modified the setdevice procedure to reset the current halftone (if
possible) when changing devices. This is necessary in the DeviceN
code because the number of device halftone components must be the
same as the number of device color model components. It is also
generally a good idea.

Fix: Default allocator added to the stable allocator because it is used
in s_zlib_alloc() when the clist is stored in memory. According to
doc/Develop.htm: "Every allocator has an associated stable allocator, which
tags pointers with the same VM space number but which is not subject to save
and restore. System VM is intrinsically stable (its associated stable
allocator is the same allocator)"

2002-10-31T16:34:01.000000Z Alex Cherepanov
Fix: Fix incorrect calculation of the clipping path around the pattern tile.
Old code used bounding box of the tile in device coordinate system as
a clippin path. When the tile was not aligned with device coordinates
the box extended beyond the tile parallelogram causing incorrect
rendering of a pattern depending on clipping path. New code draws
correct clipping path by taking advantage of high level functions.
Also gs_bbox_transform() was moved out of compute_inst_matrix()
to improve readability. Bug #595378

1. Ensuring that the process color model name is correct.
2. removing support of SeparationColorNames from additive devices.

Attached is a updated version of our code release of 4 October, 2002.
As before, the primary purpose of this release is to modify the manner
in which overprint information is passed to the overprint compositor
device. This resolves some difficulties seen when overprinting is
used with the command list device.
This update incorporates the changes checked in by Dan on October 4th.
Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
we have removed those two files from this release.

Modified Files
lib/gs_init.ps

Change "DONTPS" flag to "DOPS", with the logically inverted function:
only if DOPS is defined will "PS" XObjects be rendered. We believe this
is the more appropriate default.

Modified the deviceinfo and image code to work around a potentially
improperly set ColorValues parameter.
src/devs.mak
Updated dependency list for gdevscf.$(OBJ).
src/gdevdflt.c
1. Added initialization of the new color_info.opmode field to
gx_device_fill_in_procs.
2. In get_decode_color, added special case handling for canonical 1-bit
CMYK devices (e.g.: pkmraw). Previously the decode_color method for
this devices would default to gx_default_cmyk_decode_color, which
performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
defeat overprinting if gray object was placed on top of a colored
region.

Modified the overprint code to, when necessary, pass overprint mode
information when setting the device color. This is necessary to properly
handle overprint mode when using the command list device.
NB: This change alters the meaning of the "effective_overprint_mode" field
in the imager state.
src/gxdevcli.h
Added the opmode and process_comps fields to the gx_device_color_info
structure. These are required by the new code that passes overprint mode
information when the device color is set.
src/gsdfilt.h
Changed the prototype for the push method in the gs_device_filter
structure to match the actual implementation and usage of this method
(the third and fourth operands were reversed).
src/gsimage.c
Modified gx_image_cleanup to check if penum->info field is null before
calling gx_image_end. This avoids a crash associated that can occur if
an image has zero height or width, as the image enumeration data structure
will have been released in such cases before gs_image_cleanup is called.

2002-09-26T18:45:02.000000Z Dan Coby
The attached code release fixes a variety of memory handling problems
discovered by Dan's test with the memory validation enabled.
1. Most of the problems with the FTS were accounted for by a relatively
harmless dangling pointer problem for paths. In order to support the
charpath operator, paths are normally constructed in stable memory
(not subject to save/restore). However, clipping paths were
constructed in normal memory. If the clippath operator was used to
make the clipping path the current path, the top-level
gx_path_segments would be in stable memory, while the rest of the
path would be in normal memory. A restore operation could then
leave dangling pointers.
This is not normally a problem, because the grestore operation
associated with the restore would clear the gx_path_segments
structure. This only works on the graphic state stack, however;
graphic state objects stored in VM would not be reset.
This is harmful only in a very obscure case when the charpath operator
is used on a user-defined font whose BuildGlyph procedure contains
internal save/restore operators and which builds part of its
output with the clippath operator. As far as we know, this has
never occurred in practice.
2. Several problems noted with files 119-01.ps (panel 119-07) and
119-28.ps (panel 119-31) were caused by a problem with the memory
allocator used for the jpeg_compress_data structure used with the
DCTEncode (JPEG) filter. This filter is used by the PDFwriter, the
JPEG device drive, and as a filter accessible from PostScript.
In the first two cases the jpeg_compress_data structure is allocated
using the normal, gs_ref_memory_t structure. When used from
PostScript, however, this structure is allocated using the
gs_memory_default allocator (presumably because the jpeg library
code is not set up to deal with save/restore).
The gs_memory_default allocator is not a gs_ref_memory_t allocator,
so it does not create the hidden obj_header_t structures preceding
each allocated region. The garbage collector is dependent on these
headers, hence the pointer enumeration routines in structure
descriptors must not enumerate any pointers to memory allocated
by non-gs_ref_memory_t headers.
This creates a difficult problem for the pointer enumeration
routine of the stream_DCT_state structure, whose data.compress field
points to a jpeg_compress_data structure. This routine would have
to determine which allocator was used for this structure before
deciding whether or not to "enumerate" the data.compress pointer.
In principle it has enough information to do this (the jpeg_memory
field of the structure), but this seems like a overly complicated
solution. Use of a stable gs_ref_memory_t allocator in place of
the gs_memory_default allocator seems like a simpler solution.
3. If an overprint compositor was used with a banding device, the code
in clist_playback_band was not cleaning up this compositor before
exiting. This caused difficulty with the p2b-100.pdf file. This
code has been modified to close the target device if this device
does not match the original target device with which the routine
was invoked.
4. For historical reasons, the link between a halftone order and its
tile cache is a bit peculiar. The order includes a pointer to the
tile cache, and the tile cache keeps a copy of the order, which
points to the same levels/bit data structure of the original order.
Because of these two-way points, the order and its tile cache must
use the same memory allocator to avoid dangling pointer problems.
The code patch modifies gx_imager_dev_ht_install (gsht.c) to
preserve this invariant. The change fixes another problem noted for
p2b-100.pdf.
With these changes, we are able to run both the PS3 FTS and the full set
of pdf regression files using the '-Z@$?' switch with no reported problems.

Modified files:
src/gspaint.c
src/gspath.c
In gs_strokepath and gs_clippath, cause the newly constructed path to
use the memory allocator of the current path, rather than the memory
of the current graphic state. This is no longer strictly necessary
due to other changes that place path substructure completely in
stable memory (see gxpath.c below).
src/gxpath.c
Modify path_allocs_segments, rc_free_path_segments_local,
gx_path_add_lines_notes, and the path_alloc_segment macro to place
the entire path substructure (from the gx_path_segments structure
down) in stable memory. This is necessary to avoid dangling
pointers, as a list of path segments may be attached to another path,
parts of which were constructed with a different allocator.
src/zfdcte.c
Modified zDCTE to place the jpeg_compress_data structure into stable
memory rather than use the gs_memory_default allocator.
src/gsht1.c
Removed obsolete code.
src/gxclrast.c
In clist_playback_band, close and discard the target device on
completion of a band if it is not the same as the target device on
entry. This is necessary to remove an overprint compositor that
may have been created in the course of the band.
src/gsht.c
In gx_imager_dev_ht_install, copy any halftone orders that were not
allocated using the same allocator as used by the graphic state. This
must be done to avoid dangling forward/back pointer between halftone
orders and the associated tile caches.
Put in log files for the preparation steps: cvs update, make and install.
The cvs logs are cumulative (they can be truncated manually if desired).
These changes were in the actual running scripts until 9/18 when an update
overwrote these changes that were being tested, but were never committed.

Modified Files:
src/gsht.c
Modified the invocation of gx_device_halftone_release in
gx_ht_install to use the memory allocator pointer stored in the
device halftone, rather than the one stored in the graphic state.
src/gsimage.c
Removed what appears to have been an errant optimization in
gx_image_cleanup. This procedure will now always invoke
gx_image_end, even if the image was not rendered (penum->dev == 0).

Modified Files:
lib/gs_devn.ps
Modified the cs_install procedure for DeviceN color spaces to
support the component name array "[ All ]". The documentation
indicates that this is not legal ("PDF Reference", 3rd. ed.,
p. 206), but beginning with Acrobat 5, DeviceN color spaces with
this component name array are handled in the same manner as
Separation color spaces with the component name All. The modified
code detects this component array and converts the operand color
space to a Separation color space.

src/gsht.c
1. Fixed a memory handling problem in gx_imager_dev_ht_install,
which could result in objects being freed multiple times.
2. Removed a temporary hack in gx_imager_dev_ht_install that
ensured that the halftone cache always had at least one tile
per level. This hack is no longer necessary, as binary halftone
device colors are now handled correctly.

The attached code generalizes the sample_load_* and sample_store_* macros
in gsbitops.h to handle depths up to 64 bits. In addition to providing
64 bit versions of these macros, we also added the macros sample_load_any,
sample_load_next_any, and sample_store_next_any. These macros are intended
to be used in situations in which any supported depth may be used. All of
the invocations of the sample_load32, sample_load_next32, etc. macros have
been changed to invoke the *_any version of these macros instead. In
addition, a few minor changes have been made to silence compiler warning
messages.
Modified files:
src/gdevalph.c
Changed invocations of the sample_{load|store}_next32 macro to be
invocations of sample_{load|store}_next_any instead. Also made various
changes to allow the code to be compiled with the DeviceN system (the
file has apparently not been compiled for some time).
src/gdevdbit.c
Made a couple of minor changes to silence compiler warning messages.
src/gdevdgbr.c
Changed invocations of the sample_{load|store}_next32 macro to be
invocations of sample_{load|store}_next_any instead.
src/gdevmpla.c
Changed invocations of the sample_{load|store}_next32 macro to be
invocations of sample_{load|store}_next_any instead.
src/gsbitops.c
Changed invocations of the sample_{load|store}_next32 macro to be
invocations of sample_{load|store}_next_any instead. Also made the
value being read/written be of type gx_color_index rather than
type bits32.
src/gsbitops.h
Added 64-bit versions of the sample_load* and sample_store* macros.
Also added *_any versions of these macros, to be used in situations
where any supported color depth may be encountered.
src/gxcindex.h
Changed an invocation of the sample_store_next32 macro to be an
invocation of sample_store_next_any instead. Also updated a comment.

The modification changes the way tile depth is encoded in the command
list as part of the cmd_opv_set_tile_size command.
Modified files:
gxcldev.h
Added the macros cmd_depth_to_code and cmd_code_to_depth. These allow
encoding/decoding of the color model depth parameter (bits/pixel) in
such a manner as to support depths up to 120 bits (depths > 15 bits
must be a multiple of 8).
gxclbits.c
Modified cmd_store_tile_params to use the cmd_depth_to_code macro.
gxclrast.c
Modified read_set_tile_size to use the cmd_code_to_depth macro.

Modified files:
src/gxccache.c
1. Fixed numerous problems with compress_alpha_bits and its invocation in
gx_image_cached_char. The former procedure is called only if anti-
aliasing (text alpha bits > 1) is called for a color that requires
halftoning or for a device, such as pbmraw, that does not support the
copy_alpha method. This happens infrequently, and the code was
apparently never used.
2. Moved the invocation of gs_set_dev_color to an earlier location in
gx_image_cached_char, so that the device color will be set before
any check is made to see if it is a pure color.
src/gxclimag.c
1. Added code in clist_fill_mask to return an error if the mask to be
filled has depth > 1 and clist_disable_copy_alpha flag is set in the
disable_mask field. The latter will be the case if the target device
does not support copy alpha. The command list translates fill_mask
calls into copy_alpha calls, which drives this requirement. By
returning an error, the fall-back mechanism included in
gx_image_cached_char (gxccache.c), which is the only client of the
fill_mask method, can function properly.
2. Also modified clist_fill_mask to check that the drawing color is
pure if depth > 1 and use the default fill_mask method if this is
not the case. (The copy_alpha call to which the command list code will
translate the fill_mask works only for pure colors.) In addition, if
the color is pure, the clist_fill_mask routine will now send commands
to set color1 as well as transmit the device color; the code in
clist_playback_band (gxclrast.c) assumes that all "copy_mono" and
"copy_alpha" commands have set color1.
src/gxclist.c
Added code in clist_init_data to set the clist_disable_copy_alpha bit
in the disable_mask field if the target device does not support the
copy_alpha method. This must be done in this rather unintuitive location
because it is impossible to tell if the target device supports copy_alpha
until it has been made into a memory device (via the create_buf_device
buffer device method).
src/gxclist.h
Defined the clist_disable_copy_alpha bit, which is used in the
disable_mask field to indicate that the target device does not support
the copy_alpha method.
src/gxclrast.c
Added include of gzht.h, to silence some compiler complaints.
src/gxclrect.c
Modified clist_copy_alpha to return an error if clist_disable_copy_alpha
bit is set in the disable_mask field. This bit indicates that the target
device does not support the copy_alpha method, so we might as well
return an error now, while there is a chance the client might be able to
do something about it.

The attached code release addresses a number of issues:
1. Most of the code changes are required to turn off overprint mode when
processing images, smooth shading fills (shfill operator), or
when using PatternType 2 (smooth shading) patterns.
2. A few other changes were required to correct improper updating of the
overprint compositor information.
3. The code has been modified to avoid the crash that was observed for
the file 86554321.pdf on MSWindows XP systems.
4. The command list playback code has been modified to handle filling of
thin lines in a manner consistent with the noband case. This allows
files such as mspro.pdf to be rendered consistently in the banded and
noband case.
Jan
Modified Files:
lib/gs_img.ps
Added code to turn off overprint mode for images.
lib/gs_ll3.ps
Added code to turn off overprint mode for shfill.
src/gscolor2.c
1. Modified gs_setcolorspace to call gs_do_set_overprint rather than
invoking the color space's set_overprint routine directly. This
allows pattern color spaces to be handled (somewhat more) correctly.
2. Modified gs_setcolor to update overprint information. This is
necessary for pattern color spaces, where the color space to be used
for overprint purposes may be part of the color.
src/gscspace.c
Modified gx_set_overprint_DeviceCMYK to use the effective_overprint_mode
parameter in the image state (rather than the overprint_mode parameter
itself). This is part of the change necessary to allow overprint mode to
be turned off when a PatternType2 pattern is used as the current color.
src/gsdevice.c
Modified gs_set_device_no_init to call gs_do_set_overprint rather than
invoking the color space's set_overprint routine directly.
src/gsdps1.c
Modified rectfill to use the effective_overprint_mode parameter in the
imager state (rather than the overprint_mode parameter).
src/gsovrc.c
1. Fixed a bug in overprint_draw_thin_line: the third and fourth
operands in the call to gx_default_draw_thin_line (the y coordinate
of the first point and the x-coordinate of the second) were
in reverse order. This caused random lines to appear on various
overprint mode tests (e.g.: BEST99-00-Path.fh7.pdf,
Testform.v1.0.2.pdf).
2. Fixed typo in comment.
3. Modified the fill_in_procs procedure to initialize the device color
model information for the temporary device used in this routine.
Though the color model information does not affect the output of
the routine, reasonable values must be provided to avoid problems
when gx_device_forward_fill_in_procs calls gx_device_fill_in_procs.
This would cause certain systems to crash with files that involved
overprint/overprint mode (e.g.: 86554321.pdf on MSWinXP/MSVC systems).
4. Modified several checks that treated the separable_and_linear flag
in the device color model information as a boolean to handle this
parameter as an enumeration instead (since it is an enumeration).
src/gsptype1.c
Added gs_pattern1_set_color, the set_color method appropriate for
PatternType 1 patterns. This method performs overprint updating at
setcolor time, a requirement for patterns as the "colorspace" to be
used for overprint purposes is determined (in part) by the current
"color" (pattern).
src/gsptype2.c
Added gs_pattern2_set_color, the set_color method appropriate for
PatternType 2 patterns.
src/gsstate.c
1. Changed the criterion used in gs_grestore_only to determine if the
overprint compositor must be updated. Restoring the graphic state
may change the current color, which in the case of patterns may
change the "colorspace" to be used for overprint purposes. The code
now properly handles this possibility.
2. Added the gs_do_set_overprint routine, and modified various other
routines that directly call the current color space's
set_overprint method to call this procedure instead. The procedure
implements the special handling required for pattern color spaces,
where the current color may need to be considered when determining
which color model components must be retained.
3. Added code to initialize the effective_overprint_mode parameter in
the imager state, and provided two external routines to manipulate
this parameter. The first routine, gs_disable_effective_overprint_mode,
sets the effective_overprint_mode parameter to false, irrespective
of the setting of the overprint_mode parameter. The second,
gs_reset_effective_overprint_mode, sets the effective_overprint_mode
parameter to have the same value as the overprint_mode parameter.
The effective_overprint_mode parameter is used to turn off
overprint_mode when a PatternType 2 pattern is being used.
src/gsstate.h
Added prototypes for gs_do_set_overprint,
gs_disable_effective_overprint_mode, and
gs_reset_effective_overprint_mode.
src/gxccache.c
Modified gx_image_cached_char to invoke gx_set_dev_color before calling
(non-standard) device fill_mask methods. This handles several
situations in which a device color is not set when a cached character
is to be imaged, in particular for the command list device.
src/gxclpath.c
Added a comment to indicate that, though the overprint and
overprint_mode parameters are passed through the command list, they
usually have no effect, as overprint is controlled by the compositor
information that is (also) passed through the command list.
src/gxclrast.c
1. Added a comment to indicate that the overprint and overprint mode
parameters passed through the command list usually have no effect.
2. Added code to initialize the effective_parameter_mode field in the
imager state (though this field is usually in-effective).
3. Initialized the fill_zero_width field of the fill_params structure
in clist_playback_band to have the same value as in the noband case.
This parameter was previously always set to false, which led to
dropped lines for some files (e.g.: mspro.pdf).
src/gxistate.h
Added the effective_overprint_mode parameter.
src/gxpcolor.h
Added a set_color method to the pattern method vector. This method
performs any PatternType-specific actions necessary at setcolor
time. For now, this just updates the overprint compositor as required.
src/int.mak
src/lib.mak
Updated various dependency lists.
src/zcolor.c
Added code to disable overprint mode for PatternType 2 patterns.

Adds support for the GX_COLOR_INDEX_TYPE define to the autoconf build. The script tries a variety of likely candidates for a 64-bit type and passes the first one found through the GCFLAGS makefile variable.

This is a repeat of an earlier commit that was backed out. Its back.
Split the binary half tone cache initialization into two pieces. The halftone
cache is now initialized just prior to being used in the various halftone render
routines. This was doe to prevent a problem with cache conflicts. If the half
tone cache is not large enough for a separate tile for each level then there could
be a problem if two different device colors used the same cache entry but with
different level values.

The attached code fixes a minor problem introduced in our release
of August 26th. That release changed the behavior of the gx_path_bbox
procedure (gxpath2.c) so as to make the banding and non-banding cases
consistent. In the process we inadvertently also changed the behavior
of the pathbbox operator. This fix restores the proper behavior of
that operator.
Also included is a modified version of gsht.c for interim use. This is
not intended for final release. The gx_imager_dev_ht_install routine
is modified in this code to ensure that the halftone caches are also
made large enough to provide (at least) one tile per level. Doing so
avoids the cache overwrite bug that Dan has described, which avoids
many spurious differences in the regression test. Once Dan's fix for
the handling of the halftone tile in binary halftone colors is
installed, this version of gsht.c may be discarded.
Modified files:
src/gspath1.c
Modified gs_upathbbox to call gx_path_bbox_set rather than
gx_path_bbox. The former will return the bounding box set via the
setbbox operator, if that operator has been used for the current
path; otherwise it will return the actual path bounding box. The
latter will always return the actual path bounding box.
src/gxpath.h
src/gxpath2.c
Added the gx_path_bbox_set procedure, which will return the
bounding box set by the setbbox operator if that operator has been
used for the current path.
Temporary Files:
src/gsht.c
Modified the gx_imager_dev_ht_install procedure to always allocate
caches large enough to provide (at least) one tile per level. This
is a temporary hack to avoid a bug with the handling of tiles for
binary halftone colors. It is not intended for the final release.
Fix: Partial fix to 600855 to allow the pdfwrite (Distiller) to learn the
original font name as well as the unique font name generated by the
PDF interpreter when it copies a font and changes the Metrics and/or
Encoding. The FontName was made unique by appending a series of ? chars
until a unique name was generated. Now the suffix string itself is also
defined in the modified font dictionary with the /FontNameSuffix key.
The pdfwrite text handling needs to be modified to use this information.

We have traced the difficulties with multiple-band processing in the code
we released on Aug. 26 to two problems:
1. The halftone phase information is not adjusted for bands that
start at locations other than the top of the page.
2. The "moveto closepath" style of degenerate path, which our code
allows to be passed through the band list, is used in the path
encoding code to indicate that a path lies entirely outside the
current band (i.e.: all of the path operators between the initial
moveto and the final closepath have been skipped because they are
outside of the band). This resulted in the code passing isolated
"closepath" segments through the command list, which much confused
the band list renderer.
The attached code release fixes both of these problems, and a couple of
other more minor issues we discovered. With this change, our system has
identical output for the banded and unbanded case for the pkmraw device
at 300 dpi, for all but one FTS file (027-09.ps). In that one case, the
banded and unbanded output are visually identical, so the output difference
may not be significant. We will look into this situation, and test some
of the other devices in the next day or so.
As best we can tell, halftone phase adjustment has never been correctly
implemented for the command list device. The pre-DeviceN code handles
binary halftone colors properly, but does not set the phase for general
colored halftones. General colored halftones are much more common in the
DeviceN code, which probably is the reason Dan first noticed the problem
with FTS file 245-07.ps (and others) with the DeviceN code.

Modified Files:
src/gsht.c
Modified the code that calculates the lcm_height field of a device
halftone in gx_imager_dev_ht_install to use the full_height rather
than the height of a halftone order. This typo was introduced sometime
during the DeviceN development; the pre-DeviceN code was correct.
src/gsptype1.c
src/gsptype2.c
src/gxwts.c
Added the "get_phase" method to various gx_device_color_type_t
instances.
src/gxcht.c
src/gxht.c
Added the "get_phase" method to a pair of gx_device_color_type_t
instances. Also modified the "write" and "read" methods of these
structures to ignore halftone phase information. This information
must be passed to and be directly handled by the command list
writer code, so that the command list renderer code may correct it
for the band starting coordinates.
src/gxclpath.c
1. Modified cmd_put_drawing_color to directly handle halftone phase
information, using the new "get_phase" method of device colors.
The passing of this information must be perfomed at the command
list level, so that the command list renderer can correct the
phase for the starting point of the band.
2. Also in cmd_put_drawing_color, "unset" the saved color information
if the halftone id does not match the most recently set halftone,
rather than setting the saved color pointer to 0.
3. In cmd_put_path, when processing a segment containing a
moveto followed by a closepath, check if the moveto was to a point
outside of the current band, and discard the closepath if this
is the case. This is necessary to avoid inserting isolated
closepath segments into the command list.

This file should be identical to the version released on Aug. 22nd.
We are releasing again here just to guard against this code being

These files are identical to the set released on Aug. 23rd (the fix
for color changes in a kshow procedure). We are releasing them again
here to make certain the rest of this code is not committed without
the former change.
src/gxacpath.c
Modified gx_cpath_accum_end to set the new bbox_accurate field rather
than the bbox_set field. This avoids overloading the bbox_set field
in a way that can lead to inconsistent output when the setbbox
operator is used with a path.
src/gxcht.c
src/gxht.c
src/gxdcolor.c
src/gxdcolor.h
Modified the "write" methods for various color spaces so that their
return value can indicate that the operand and last transmitted
colors are the same. Also fixed various bugs uncovered when the
modular device color serialization/de-serialization was first used.
The changes to gxdcolor.h involve only comments.
src/gxcldev.h
1. Added a saved device color (gx_device_color_saved) to the band
state structure.
2. Removed the (long since unnecessary) type operand from the
cmd_put_halftone procedure.
3. Commented out some now obsolete command codes.
src/gxclimag.c
1. Modified clist_fill_mask to work with the new, modular drawing
color serialization/de-serialization routines.
2. Rewrote cmd_put_halftone as required by the new mechanism for
serializing/de-serializing device halftones.
3. Modified various invocations of cmd_put_halftone to discard the
the type operand.
Note: The existing code impose a requirement that image objects that
used a device color (e.g.: image masks) would only be passed
through the command list if that color is pure. We do not
know why this limitation was necessary, and suspect it is no
longer necessary, but we have left it in place for now.
src/gxclist.c
Added gxdcolor.h to the included file list.
src/gxclpath.c
1. Rewrote cmd_put_drawing_color to use the new mechanism for
serialization/de-serialization of device colors.
2. Removed the device color type information from the stroke/
fill/polyfill commands.
3. Modified cmd_put_path so that "moveto closepath" is not
passed through the command list as just "moveto".
src/gxclpath.h
1. Added the cmd_opv_ext_put_ht_seg, to allow device halftones to be
split across multiple command buffers. Also added the macro
cbuf_ht_seg_max_size, to indicate the largest halftone segment to
be put in a single command buffer.
2. Commented out some now obsolete command codes.
src/gxclrast.c
1. Modified the code to read device halftones and device colors to
use the new serialization/de-serialization methods for these
structures.
2. Modified various locations in which partial/temporary device
colors are used to use the current color for the band.
3. Removed code for the various stroke/fill/polyfill commands that
encode device color type as part of the command.
4. Added code to save the current color when a pure color must be
set to generate a clip region using the fill procedure.
5. Modified the clip path reading code to flatten the clip path
before passing it to the fill operation. This is necessary to
ensure consistent results between the banded and non-banded
cases (the non-banded case also flattens a clip path before
passing it to the fill operation).
src/gxdhtserial.c
1. Updated gx_ht_read_tf and gx_ht_read_and_install to properly
use the reference count in a transfer function.
2. Fixed various other errors discovered when this code was first
used.
src/gxdhtserial.h
Fixed typo.
src/gxpath.c
Initialize the new bbox_accurate field of the gx_path structure to
false in gx_path_init_contents.
src/gxpath2.c
Modified gx_path_bbox to use the bbox_accurate rather than bbox_set
field to determine if the bounding box of a path needs to be
explicitly calculated. If bbox_set is true, the bounding box
in the bbox field will contain the current path, but may be larger
than necessary. Due to a problem in the clip/fill code, the larger
bounding box may generate slightly inconsistent results.
src/gzpath.h
Added the bbox_accurate field to the gx_path_s structure. This field
is used by the clip accumulator device, which avoids the need to
overload the bbox_set field (which is also used by the setbbox
operator).
src/lib.mak
Updated varius dependency lists.
Modified files:
src/gstext.h
src/gstext.c
Added the routine gs_text_update_dev_color, to update the color
used for drawing text if this changes during a text operation
(e.g.: due to the action of a kshow or cshow procedure).
src/zchar.c
Modified op_show_continue to call gs_text_update_dev_color in case
a cshow or kshow procedure changed the current color (strictly
speaking, this is only a problem with kshow).

Modified files:
src/gsht.c:
In gx_imager_dev_ht_install, the comp_number field in the entries
for the newly allocated components_array was improperly assigned,
due to a typo. Later code checks if the comp_number value matches
the component index and, if not, uses the default halftone order
for this component. This would cause a typical 4-color device to
always use the default halftone component (and leak memory).
As part of the same fix, some redundant code in gx_imager_dev_ht_install
has been removed, and the code that updates the "used_default" variable
in this procedure has been corrected.

Fix: The addition of the function sampling logic for DeviceN tint
transforms (fix 474544) tripped over a bogus assumption in Adobe Procset
for DuoTones generated by (at least) Photoshop. The assumption was that if
the alternate color space of a DeviceN space was being used, that the
procedure would run when 'setcolor' was executed and that the stack would
be accessible during that procedure. This fixes several bug reports with
'/stackunderflow in pop' errors including SF #549307, 576577 and 582385

Changes all references to L. Peter Deutsch as the author of Ghostscript to

Ghostscript.
Fix: Adobe renders marks outside the ImagingBBox and QuarkXPress relies
on this. Maintain the ImagingBBox of the page device at the PostScript
level independently from the device parameter. There is a slight
incompatibility if programs that set the ImagingBBox incorrectly relied
on this causing clipping, which is prohibited by the PLRM. Programs that
wish to directly set the ImagingBBox device parameter can still do so
from C or from PS using the .putdeviceprops GS private operator.

Fixes the last (?) major batch of problems in the new pdfwrite text code.
We think this code is now good enough for general testing: search for PDTEXT
in src/devs.mak for information on how to enable it.
Fixes bugs in font copying (currently used only by the new pdfwrite text
code): TrueType glyphs with multiple names in CharStrings only stored a
single name; copied Encodings were initialized incorrectly to .notdef rather
than GS_NO_GLYPH; some of the procedures of copied TrueType fonts weren't
initialized correctly; 'seac' didn't copy the Encoding entries for the
components. Also shares the known glyph names when possible, to reduce the
load on the garbage collector.
[src/gxfcopy.c src/gxfcopy.h]
2002-07-09T14:04:19.000000Z lpd
Adds a procedure for testing whether a string was returned by
gs_c_glyph_name. Allows the font copying code to share these strings,
substantially reducing the load on the garbage collector.
Fix: MSVC can't handle a makefile that compiles two sets of code with some
of the same exported names, but only linked in one set. The fix still
requires a 1-line edit of devs.mak when using MSVC.

Fix: The hmtx/vmtx tables generated from the glyph metric data for embedded

Fix: If the 'resourceforall' operator's procedure operand gets an error or
performs a 'stop', Adobe interpreters return an operand stack with the

Adds a complete rewrite of the font and text code in pdfwrite, based on
copying fonts incrementally to stable memory rather than trying to deal with
fonts being freed at unpredictable times. Should fix a large number of
current SourceForge bugs when completed: however, the code is currently in
pre-alpha state and is not usable on any realistic input. The API is
compatible with the previous pdfwrite text code; the choice of which set to
use is controlled by a single, documented line in src/devs.mak.

Patch by Rod Webster (rodw). SF#559565
Fix: Wrong Widths array entry could sometimes be used when the
Encoding (after Differences applied) mapped codes to the same
glyph. Logic introduced in rev 1.22 only prevented some of the
incorrect Width. Fixes SF bug# 570784 for Artifex customer #150.

Fix: Fixes regressions caused by previous update including errors with
ImageProb2*.pdf and aaon97_p7.pdf. Removes logic that set StandardEncoding
if BaseEncoding wasn't set since this caused aaon97_p7 regression. Only
use .notdefEncoding if updateencoding sees a null encoding input. This
is the "real" fix for SF bug #566042.
[lib/pdf_font.ps]
2002-06-21T07:46:37.000000Z Ray Johnston
Fix: Previous fix for SF bug #566042 caused a regression by defining an

when we need to update it with /Differences. Some regression files were
onechar.pdf, xngnews.pdf. The testfont.pdf file of 566042 still runs OK.
[lib/pdf_font.ps]
2002-06-21T06:49:50.000000Z Ray Johnston
Fix: Prevents /typecheck in --length-- if given a file with an Encoding
dictionary with a Differences list has no BaseEncoding. This is perfectly
legal -- the base encoding is the font's built-in encoding or
StandardEncoding, per the PDF Reference (depending on whether or not the
font is flagged as "symbolic"). Fixes SF bug #566042.

Fix: pdfinflt.ps should not propagate the /Prev from the input file's

[src/gxfont42.h src/gstype42.c]
2002-06-18T22:50:51.000000Z lpd
Changes the writing of embedded TrueType (and CIDFontType 2) fonts so that
hmtx/vmtx are written only if the font already includes a hhea/vhea table.
This is not a perfect solution, but it is better than always writing both
hmtx and vmtx, because a TrueType rasterizer cannot make use of the *mtx
table without the corresponding *hea table.
Fix: Correct the pdfformaterror message issued when an 'endobj' is seen
instead of 'endstream' and add a comment in the file about the error.
Thanks to Dan Coby for the suggestions improving the previous patch.

2002-06-18T00:31:20.000000Z lpd
Fix: psf_write_truetype_font and psf_write_cid2_font copied hmtx and vmtx
rather than getting the actual metrics through the font virtual procedures,
which produced incorrect output if the font was defined incrementally and
used MetricsCount. (This only affected pdfwrite.)
Fix: Because of a bug introduced by the removal of known_encode, accented

2002-06-09T23:08:23.000000Z lpd
Cleans up a number of design problems in the font callback procedures:
1) Eliminates the gx_xfont_callbacks structure entirely. The known_encode
procedure is no longer needed: the new facilities in gscencs.[hc] make it
unnecessary, and none of the three implementors of the xfont interface
use it. See below regarding glyph_name. This is a NON-BACKWARD-
COMPATIBLE change for all clients of the glyph_name and known_encode
procedures (of which there are, respectively, 11 and 0 in the current
code base), and for all places that define gs_font_procs structures
statically or initialize the callbacks dynamically (of which there are
currently only two, one in gsfont.c and one in zbfont.c). There are also
3 identical places in the GhostPCL code (in plfont.c, plffont.c, and
plufont.c) that will require very minor changes, with a small net
reduction in code.
2) Deletes the char_xglyph2 procedure from gx_xfont_procs. It is optional,
and none of the three current xfont implementations implements it.
3) Changes the char_xglyph procedure in gx_xfont_procs so that instead of a
glyph_name callback procedure, it takes a const gs_string * argument that
is the actual glyph name (if the glyph is not gs_no_glyph and is not a
CID). This is a NON-BACKWARD-COMPATIBLE change for both clients and
implementors of xfonts. (At present, there are 3 implementors, none of
which use the glyph_name callback, and a single client call in
gxccache.c.)
4) Moves the glyph_name procedure, which is still required for other
purposes, to gs_font_procs, changing its declaration to
int (*glyph_name)(gs_font *font, gs_glyph glyph,
gs_const_string *pstr);
This is a NON-BACKWARD-COMPATIBLE change for clients, but they must
already change because of item (1) above.
5) Eliminates the registered_Encodings array in the PostScript interpreter,
substituting the C representation of the known Encodings.
Fix: enumerate_glyph would crash if applied to a subfont of a CIDFontType 0
font. (Probably only affects font copying, to be used in the future by
pdfwrite.)

Simplifies the C implementation of the known Encodings, and makes it conform
better to Ghostscript standard coding style.
gs_exit() cleanup.
gs_exit() is renamed gs_to_exit() since it is an about to terminate cleanup
function, it always returns.
Both gs_to_exit() and gs_abort are client provided functions. The client
can have its own special cleanup on exit, and the client can decide what it
wants to do in the abort case: exit, setjump/longjump, ...
gp_do_exit() is the way for the client to call a system independent exit()
this allows for different exit codes on unix and vms for instance.
Only the client can call this, if so desired from their gs_abort().
Changed END_OBJECT_SCAN to call gs_abort() instead of gs_exit in a debug
system when a chunk parsing error occurs. If gs_abort() is never to be
called such as during a debug dump END_OBJECT_SCAN_NO_ABORT can be called.

2002-05-07T19:56:46.000000Z lpd
Fix: pdfwrite could not convert a CIEBased color space with input domains
larger than [0..1] to an ICCBased space, because the ICC profile
specification inherently limits inputs to this range. The fix required
explicitly rescaling the decoding of the color data in many different places
when such a color space was involved: the Decode arrays in images; the
tintTransform functions for Separation and DeviceN color spaces; the
Background, Function, and Decode for shadings. While this was only a
performance problem, it could be a very severe one, because it caused images
using such extended-domain CIEBased spaces to revert to zillions of tiny
rectangles. This change completes the ability of pdfwrite to convert
PostScript color spaces, aside from DeviceN and Separation spaces which are
the subject of a separate project.
Fix: A rounding problem made installation of CIEBased color spaces
non-idempotent, which could cause seriously incorrect rendering of CIEBased
colors in the sequence [/CIEBased...] setcolorspace, gsave, [/Pattern
[/CIEBased...]] setcolorspace, grestore. Fixes SourceForge bug #547695,
q.v.

Fix: If a shading's Function entry was an array of functions rather than a
single function, pdfwrite wrote out an invalid Function object with a
FunctionType of -1.
[src/gdevpdfu.c src/gsfunc3.c]
2002-04-14T04:30:47.000000Z lpd
Fix: Indexed color spaces weren't implemented for ShadingType 4-7 shadings.
Fix: ShadingType 1 shadings whose Function was an array required the
individual functions to take 1 argument, rather than the correct 2; shadings
whose Function was not an array didn't check that the function took the
correct number of arguments. (The Genoa FTS does not check either of
these.)

Fix: Adding any of the base 14 fonts to the NeverEmbed list produced broken
output in PDF level 1.3 and above. Makes the 'default', 'screen', and
'ebook' parameter sets not embed the base 14 fonts. (The documentation
already said this was the case, even though it wasn't.) This is a partial
fix for SourceForge bug #438957.

Fix: gscheck_pdfwrite.py was modeled after run_regression instead of
check_*.py. This corrects the script so that it follows the testing
conventions and also adds gscheck_all.py which will run every gscheck_*.py
test (of which currently there is only one).
Adds gscheck_pdfwrite.py and a new test class, GSFuzzyCompareTest. This
test does fuzzy compares of ps->raster and ps->pdf->raster to help
ensure the pdfwrite device is functioning properly.
Fix: The recently added reference to zcidtest.c had the correct text but an
incorrect URL.

Fix: Changes the operation of AutoFilter{Gray,Color}Images to always use the
lossless filter (normally FlateEncode), rather than using DCTEncode for
8-bit-per-component images at least 64x64 in size. While this isn't
optimal, it fixes a long-standing problem that many users have complained
about. Fixes SourceForge #450663.

Changes gs_cmap_t (internal representation of CMaps) to an abstract
superclass with multiple implementations: standard Adobe CMapType 1,
TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
that composite fonts (including those based on TrueType Unicode fonts) with
Unicode-based CMaps are embedded in the PDF file with the original text
preserved and with an appropriate ToUnicode CMap, making the text searchable
in Acrobat.
Fix: Compiling with -dPROFILE could cause compiler warnings about "memxxx
redefined" (memset, memcpy, etc.).

Update changelogs for 7.20rc2. These are actually incomplete pending a
bug in cvs2hist.
Adds support for compilation against a standard shared libjpeg. It
is believed that non-baseline compliant DCTEncoded data, permitted by
early versions of postscript, is now extremely rare and the prohibition
against SHARE_JPEG=1 may reasonably be removed. The autoconf build will
prefer a local copy of the jpeg source, in which case the
D_MAX_BLOCKS_IN_MCU patch will still be applied. If no such local copy
is found, it will try to find a shared library on the system. For all
unix builds, if $(JSRCDIR)/jmemsys.h cannot be found, we define
DONT_HAVE_JMEMSYS_H and include our own versions of the libjpeg memory
manager prototypes. The default allocator in the shared library is
overridden by the ghostscript one at link-time. While this may be
implementation-dependent, it appears to function as desired on at least
GNU/Linux and Solaris.
Also changes the autoconf build to prefer local zlib and libpng source,
and cleans up some variable names.
Adds DELAYSAFER/.setsafe logic to pdf2dsc output, as needed for a
security update to gv.

Fix: removes gcc-specific compiler flags from the autoconf makefile,
including the -fomit-frame-pointer optimization. Replaces the workaround

Replace Windows icons with new versions that include 48x48 pixel

update the documentation on supported libpng versions

Updates the default version of the PNG library to the most-recent 1.2.1.
Likewise updates references to the zlib version to the more recent
1.1.4, which includes an important security fix. Updates the default
paths to the library source trees in all-arch.mak to reflect current
usage.
Fix: verify that our default collection of compiler switches
(gcc-specific) work before using them. This allows the autoconf build to
work with non-gcc compilers. Completes the fix for SF Bug #514898.

Implementing Visual Trace service to graphics library,

Makes 'save' create inner chunks for all chunks with at least a minimum

fonts that push more than 48 elements on the ostack from overflowing the

Fix: epswrite generates "grestore gsave" while changing a clipping path,

Fix: When pdfwrite embedded a TrueType font with a generated format 6 cmap,
it incorrectly added the character bias (0xf000) to the "first character

some others. This fix also adds a set of compile-time options for forcing
embedded TTFs into particular formats for debugging.

Fix: For images specified in general CIEBased color spaces, pdfwrite would
divide the image into tiny rectangles. If the output level is PDF 1.3 or
higher, pdfwrite now converts the CIEBased color space to an ICCBased space
if possible.
Updates pdfwrite to match Acrobat Distiller 5 more closely: adds
OffOptimizations and PreserveEPSInfo parameters; adds /ebook value for
PDFSETTINGS; changes some of the DCTEncode parameter values for
auto-filtered images; adds CreationDate and ModDate in Info dictionary;
always subsets non Type 1 fonts.
Fix: CIE color conversion could be very inaccurate if it didn't use
interpolation when cached sampled values were near zero. This fix detects
numerically sensitive areas and uses interpolation (which is computationally
expensive) only in those areas. Fixes SourceForge #465921.
Adds extensionless aliases for all the scripts used in the normal build

a problem detected by the regression testing. This was found with test
file 035-01.ps. Both problems were caused by an error in the logic for
comparing two halftones for equality. This logic is used to determine
which the halftone cache needs to be reloaded. In both cases, non equal
halftones were being considered equal.
Remove hardcoded paths from run_regression and eliminate need for external
command 'md5sum'. We now use the 'md5' python module which does the same
thing.
Fix: Trailing comma in structure (compile error on AIX).

Fix: Image DataSource procedures that did save/restore would clear the
tile cache which was not detected in image_render_mono resulting in
images being painted with (mostly) all black when the device was a
halftoned device e.g. pcxmono or tiffg3. Check for vailidity of the
ht_cache and re-init the image color clues if not valid. Also improve
performance by preventing restore from always clearing the ht_cache.

Refactors the CIEBased color mapping code slightly to make the CIE => XYZ
step separately accessible. (The XYZ => device step is already exported for
rendering ICCBased color.) pdfwrite needs this for converting arbitrary
CIEBased spaces to ICCBased.
Replaces references of 'FontManagerLib' with 'FontManager' to match the Universal Headers
stub shipped with Metrowerks CW 6.3. Also disables the warning about unused arguments
since we have a lot of those be design and they accounted for the majority of the

Changes all procedures for getting glyph outline data to return a structure

These changes were originally put into the GS_6_5 branch on 2001/03/13.
They are needed for using the current version of teh graphics library
with the PCL6 code.
Short description of changes:
stat_.h: Added definition of stat_is_dir for use with MSVC. Not
used in Ghostscript.
gsptype1.c: Changes in image_PaintProc. This routine is used
in gs_makepixmappattern. gs_makepixmappattern is only used in
test8 (in gslib.c - a test module) and gs_makebitmappattern_xform.
gs_makebitmappatern_xform is not used in Ghostscript. It is
used in pcl6.

Fix: pdfwrite didn't write transfer functions in the output for images, and
allowed lossy compressions on images even in the presence of peculiar
transfer functions (such as functions simulating indexed color spaces).
This fix writes transfer functions for images, prevents lossy compression if
the transfer function is not the identity, and undoes the hack that was
implemented earlier to work around this problem. Fixes SourceForge bug
#420257.
Fix: The algorithm for scaling down user coordinates to fall within Acrobat
Reader's limitations didn't work properly for stroked paths with anisotropic
CTMs, possibly producing large coordinates that led Acrobat (but not
Ghostscript) to display the resulting file incorrectly. Fixes SourceForge

Patch from Mr. Toshiya Suzuki :
Implementing multi-dimensional CID ranges, and fixing bugs
about decoding text string with CID font :
(1) when GS consumes undefined byte sequence (which cannot be mapped
to some glyphs), GS aborts.
(2) when selected CID font lacks the glyph for requested CID, GS aborts.
(3) "notdefrange" defines SINGLE CID for undefined byte sequences
in specified range, but current GS implementation take it as
an offset to calculate MULTIPLE CID.
(4) "cidrange" operators accept only
full range specification (<0000> to )
or 8 bit width range ( to ).

This file is a new utility intended for debug.
It is not yet ready for prime time, but is available for whoever
wants to fix it.
The main problems are:
1. It doesn't work for files that use chained filters such as
[ /ASCII85Decode /FlateDecode ]
2. The PDF files that are written are sometimes broken. GS gets an
xref problem.
This second problem may actually due to lib/pdfwrite.ps since
even when no conversion is done, the file is bad.

Fix: Optimization for shading fill.
The general path filling algorithm subdivides fill region with
trapezoid or rectangle subregions and then paints each subregion
with given color. If the color is shading, each subregion to be
subdivided into areas of constant color. But with radial
shading each area is a high order polygon, being
subdivided into smaller subregions, so as total number of
subregions grows huge. Faster processing is done here by changing
the order of subdivision cycles : we first subdivide the shading into
areas of constant color, then apply the general path filling algorithm
(i.e. subdivide each area into trapezoids or rectangles), using the
filling path as clip mask.

Fix: This IdiomSet replaces 3 procedures generated by Win2K driver in level
1 mode for RGB source image and DeviceRGB, DeviceCMYK, and DeviceGray color
models. Original implementation uses transfer functions to simulate the indexed
color space. Currently, GS always ignore transfer functions. The replacement
procedure uses indexed color space directly. This Idiom should really be in
a file in the IdiomSet directory of the Resource path, but we put it here until
GS has a way to handle distribution and installation of Resources.

Minor fixups related to the decision to use two-digit minor numbers
consistently.
Fix: Setting an ICC color space now invalidates the joint cache, so that
TransformPQR gets computed. The profile is explicitly loaded so that the
TransformPQR procedures have access to the white point. Also, the
photometric interpretation of the hack for /All separation color spaces
is reversed. Fixes Fixed_Original.pdf from Michael Jahn and Adobe tech
note 5002_EPSF_Spec.pdf.
Fix: Need a cast to (gs_memory_t *) to prevent errors on some compliers.
Change provided by Nelson H. F. Beebe.

Fix: AR4 doesn't like fonts with empty FontBBox which happens when the font
contains only space characters. Small BBox causes AR 4 to display a hairline.
So we use the full BBox.

Fix: Ghostscript should return to the caller, not exit.
Remove exit() from gp_do_exit() for all platforms except VMS.
Fix: two small issues with compilation under xlc on IBM AIX RS6000, a name

Changes default XLIBDIR and XINCLUDE to /usr/X11R6, which is far more
likely than the previous values.
Fix: Genoa FTS 035-07.ps got a SEGV error caused by data being allocated
in non-GC memory, but pointer enumumeration giving these pointers to the
GC for tracing. Since these objects didn't have GC type headers bad things
happened. Also change one of the allocations in sjpegc.c to immovable that
was not -- this change was not needed to prevent the crash.

Various documenation fixups.
Removes pointer to external pdf_sec.ps now that the full implementation is in our distribution.
Adds note on the class="offset" attribute to the html style guidelines.
Fix: Do not put Windows stdin into binary mode if it is the console
because this returns CR and LF each time the Enter key is pressed.
This caused Ghostscript to not pause at following showpage prompts.

updates to support libpng v1.0.10.
OS/2 makefile fixup for v1.0.9 and above from Russell Lang.
Fix: Set default size of MAX_ESTACK to 5000. This is the minimal fix

2001-04-01T01:10:55.000000Z Raph Levien
Updates dates in preparation for 6.63 beta release. News updated.
Change: The Ghostscript 'pwrite' function name conflicted with the
standard pwrite function defined in unistd.h on several systems.
To avoid confusion with the standard function change the name to
stream_write. Also change 'pputc' to 'stream_putc' and 'pputs' to
'stream_puts'. Fixes SourceForge bug #410772. Fix by Ray Johnston.
Fix: Adds imaging_dev field to text enumeration, so that bbox device can
intercept low level drawing operations caused by implementation of
forwarded high level text operations.
Applies PDF 1.4 rendering with all devices. Previously, only pnga device
contained PDF 1.4 rendering capabilities. Now, when the PDF 1.4 imaging
model is detected in the source file, it installs the pdf 1.4 rendering
device as a device filter.
Fix: Put Windows console stdout and stderr in binary mode.
Ignore the initial callout for stdout and stderr as the
procedure stream acquires a buffer.

Fix: Correct memory allocation problems in the display device.
Return correct pointers from display_enum_ptrs so that the
memory device and bitmap are not moved or prematurely freed.
Adds a finalize procedure.
Change the memory device to not forward to the display device.
Mark the memory device as retained so it gets freed at the
correct time.
[src/gdevdsp.c src/gdevdsp2.h]
2001-03-29T04:09:40.000000Z rayjj
Fix: Changes to introduce the min_left stream state variable set this to
1 for procedure streams, which caused 1 character to be retained in the
stream buffer which was not passed to the client. This broke the DLL
interface where procedure callouts were used to get the string from the
callback. Procedure streams have no need for EOD lookahead (to force
closure) so the correct min_left value is 0. SourceForge bug #404331.

2001-03-28T21:50:56.000000Z Alex Cherepanov

2001-03-26T11:28:20.000000Z Russell Lang
Adds %printer% device to Windows to allow a printer to be specified

"\\spool\Printer Name" for all but Windows 3.1/Win32s.
Unlike the old \\spool\, the new %printer% device does not
write a large temporary file.

Adobe Acrobat Reader ignores this. Generally speaking, Ghostscript does
not attempt to accept files that grossly fail to obey the Adobe

is easy and unlikely to break anything. SourceForge bug #406694.

[doc/API.htm doc/DLL.htm doc/Readme.htm]
2001-03-13T07:09:29.000000Z Russell Lang
Implement new Ghostscript interpreter API for DLL or shared object.
Reimplement old DLL interface using new API.
See iapi.h and iapi.c for new API.
For unix, build using "make so".
Added loader programs for Ghostscript interpreter library
for Linux (dxmain.c), Windows (dw*.c) and OS/2 (dpmain.c).
Add new "display" device for use with the new API.
Linux dxmain.c uses the "display" device, Gtk+ and GdkRgb
for faster drawing than the "x11" device.
Redirect all user messages from stdout and stderr to outwrite() and
errwrite(). This is needed to allow stdout/err to be redirected to
the caller for DLL / shared object builds.
Fix: GS didn't accept packed array as data source in image with
multiple data sources. From internal bug report.

Adds Epson Stylus Color 300 support to uniprint, also some code cleanups.

Fix: Speed-up JPEG decompression by increasing file buffer to 2K. This
avoids installation of an intermediate buffering filter that resulted in
a byte-by-byte filling of the buffer to the JPEG code. When the buffer was
not full enough a recoverable error would result in a round trip for the
next byte. Fixes SourcForge bug #405342 for Artifex customer #350.

Adds support for localized manpages to the make 'install' target. On unix
the makefile will now intall any files with the $MAN1EXT extension it finds
under locale subdirs of the man directory that are listed in the MAN_LCDIRS

Adds a '-t' option to enable text output rather than html, replacing the

output.

The PDF specification says that the 'xref' must be on a line

Fix: Embedded CIDFontType 2 fonts had an incorrect BoundingBox.
[src/gdevpdff.c]
2000-12-08T23:35:38.000000Z lpd
Extensively revises and updates the pdfwrite text handling code to support
processing and embedding of all types of fonts (except for Type 3 and
CIDFontType 1, which are defined by PostScript procedures), and all variants
of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with
all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both
standard and non-standard CMaps are supported.
Fix: The PDF interpreter ignored the CIDToGIDMap entry in (embedded)
CIDFontType 2 fonts, producing incorrect output if the map wasn't /Identity.

Fix: The font_info procedure for PostScript fonts other than Type 1 didn't

[lib/pdf_font.ps]
2000-12-02T20:39:37.000000Z lpd
Fix: 'gstate' was allowed in global VM even if the current graphics state
included references to structures in local VM (which is, in fact, normally
the case) and the save level was non-zero: this could create a dangling
pointer after the 'restore'. This "fix" is a workaround that simply
prohibits doing this, but a correct fix would copy any such structures.

Fix: Further tweaking of the logic to clear end_status flags in a

Fix: Type 1 CharStrings loaded from disk for type 0 CIDFonts were never
freed, except by garbage collection (which doesn't reclaim chunks with only

Adds a tool to check whether a document mentions all the files in a set of
directories, and uses it to fix a few incorrect links in the developer

Fix: More robust %%EOF handling. When %%EOF in PDF file doesn't end with a
line terminator. GS fails with /invalidaccess in setfileposition because
readline closes the file . This fix replaces readline with readstring and

2000-10-19T23:46:46.000000Z lpd
Fix: WMode was generally ignored in handling the metrics when rendering a
Type 1 or Type 2 CharString; also, the default metrics for WMode = 1 were
the same as the default metrics for WMode = 0, whereas (at least for
CID-keyed fonts) they should be computed from the FontBBox. (fix from
igor@artifex.com)
Fix: The PDF interpreter didn't skip garbage bytes between the last data
byte of an in-line image (ID operator) and the next end-of-line. While this

Revises the font substitutions slightly to improve the quality of the
matching.
[lib/gs_fonts.ps]
2000-10-17T14:41:35.000000Z lpd
Fix: Mapping of CIEBasedDEF[G] colors was incorrect. The original code used
pcie->Table.dims[i] instead of
pcie->caches_defg.DecodeDEFG[i].floats.params.factor as the domain of the
DEFG table, so all colors were scaled down by a factor of about 100. Also
added interval narrowing before indexing for greater stability. (fix from

Adds code for constructing a Lab space to substitute for any CIEBased space

In order to work around the ADOBEPS4 Windows driver's habit of defining
/.notdef as {pop 0 0 setcharwidth} in otherwise well-behaved Type 1 fonts,
which prevents the PDF writer from embedding the font, recognizes this
construct as a special case and converts it to a Type 1 CharString (0 0 hsbw
endchar).

version didn't even compile), except for TransferFunction.
[src/ztrans.c]
2000-08-30T15:03:36.000000Z lpd
Completes the parsing of .{begin,end}transparency{group,mask}, except for
the TransferFunction for masks. The specification is still subject to
change.
If a PDF file is invalid but repairable, prints out the Producer as part of
the warning message.
[lib/pdf_main.ps]
2000-08-24T03:43:12.000000Z lpd
Adds a project to avoid DCT-decoding followed by DCT-encoding images when
writing PDF files.
[doc/Projects.htm]
2000-08-24T03:04:29.000000Z lpd
Implements the new PDF 1.4 scalar graphics state parameters (ca, CA, SMask,
AIS, BM, TK). The implementation of SMask is a stub.
[lib/pdf_draw.ps lib/pdf_ops.ps]
2000-08-24T03:03:18.000000Z lpd
Fix: The stub implementations of .{set,current}{opacity,shape}mask didn't
{pop the argument}{push null}.
[src/ztrans.c]
2000-08-24T02:26:52.000000Z lpd
Implements the op, OP, and OPM (overprint control) elements of ExtGStates.
[lib/pdf_draw.ps lib/pdf_ops.ps]
2000-08-24T01:55:37.000000Z lpd
Fix: Setting the color (fill or stroke) sometimes overwrote the color
associated with an outer gsave level.
[lib/pdf_ops.ps]
2000-08-23T21:46:31.000000Z lpd
Starts to implement the PDF 1.4 transparency features. All API and operator
additions are now implemented (at least as stubs) and documented, as is
bookkeeping for the new scalar graphics state members (but not for the soft
masks or the transparency group stack).
Fix: The emulation of XPutImage (Ghostscript*useXPutImage: 0) was broken.
[src/gdevx.c]
2000-08-21T14:43:17.000000Z lpd
Fix: BJC printers with different X and Y resolution produced incorrect
output. Also removes the comment asking users to report problems to Yves
Arrouye, since he no longer maintains this code.
[src/gdevcdj.c]
2000-08-21T14:38:28.000000Z lpd
Changes text to make it clear that Yves Arrouye no longer maintains the BJC
drivers that he wrote.
[doc/Devices.htm src/contrib.mak]
2000-08-20T00:21:42.000000Z lpd
Fix: gdev_vector_dopath could return 1, which value was then propagated to
callers that interpreted it differently.
[src/gdevvec.c src/gdevvec.h]
2000-08-20T00:20:42.000000Z lpd
Notes the change in the return value of gdev_vector_dopath.
[doc/News.htm]
2000-08-19T03:31:44.000000Z lpd
In the X Windows driver, changes XFlush() to XSync(False) so that updates
will actually complete before the command prompt appears.
[src/gdevx.c src/gdevxini.c]
2000-08-19T03:01:30.000000Z lpd
Fix: Parameter lists didn't have proper GC descriptors; garbage collection
could mangle keys and collection values in non-transient parameter lists
(such as distiller parameters).
[src/gscparam.c]
2000-08-18T03:20:12.000000Z lpd
Fix: The *ACSImageDict parameter dictionaries weren't being set for the
/default configuration; the *ACSImageDict parameters were never recognized,
because their names were spelled incorrectly as *ACSDict. (Two separate
bugs.)
[lib/gs_pdfwr.ps]
2000-08-18T03:18:59.000000Z lpd
Fix: Setting parameters for the PS/PDF writer reset any unspecified *Dict
parameter dictionaries to the empty dictionary, rather than leaving them
alone.
[src/gdevpsdp.c]
2000-08-17T20:43:50.000000Z lpd
Adds a mention of the Color LaserJet 4500 as a color PCL XL printer.
[src/devs.mak]
2000-08-17T17:00:42.000000Z lpd
Fix: the "User parameters" section was incorrectly titled "Device
parameters".
[doc/Language.htm]
2000-08-17T04:43:25.000000Z lpd
Fix: the user-contributed cfax driver didn't correctly handle page widths
other than the standard fax widths, and didn't write the required
end-of-document marker.
[src/gdevcfax.c]
2000-08-17T01:31:52.000000Z lpd
Documents the -dDEVICE{WIDTH,HEIGHT}POINTS= switches.
[doc/Use.htm]
2000-08-16T01:26:22.000000Z lpd
Fix: s_add_filter used min_out_size rather than min_in_size for the minimum
buffer size, which could cause an endless loop when writing to the filter.
(This only affected filters allocated by C code, not by the PostScript
filter operator.)
[src/stream.h src/stream.c]
2000-08-09T16:55:25.000000Z lpd
Fix: The FlateEncode and zlibEncode filters didn't implement the "Effort"
parameter. (fix from Alex Cherepanov)
Fix: PDF files with embedded CID fonts with FontName != BaseFont (prohibited
by the PDF specification, but produced by some Adobe software) caused an
error.
[lib/pdf_font.ps lib/pdf_ops.ps]
2000-08-07T20:41:45.000000Z lpd
Checks in the final set of changes for this fileset.
[doc/Changes.htm doc/History6.htm]
2000-08-07T17:52:22.000000Z lpd
Adds some missing dependencies.
[src/lib.mak src/int.mak]
2000-08-07T17:48:10.000000Z lpd
Updates dates and version #s for the 6.23 fileset.
Fix: 'pre' didn't work with dates in August or September (Tcl doesn't accept
08 and 09 as valid numbers).
[toolbin/pre]
2000-08-07T17:22:27.000000Z lpd
Changes 'gsmake' to report line number rather than character position for
errors and warnings.
[toolbin/gsmake.tcl]
2000-08-05T01:04:28.000000Z lpd
Fix: "Accurate curves" was a no-op for certain cases of horizontal or
vertical tangents.
[src/gxpcopy.c]
2000-08-04T16:09:30.000000Z lpd
Fix: Showing text with a singular matrix (scaling matrix x CTM) could leave
extraneous values on the operand stack.
[src/zchar1.c]
2000-08-04T16:08:05.000000Z lpd
Fix: Setting a singular text matrix (e.g., 0 0 0 0 Tm) caused an
error.
[lib/pdf_ops.ps]
2000-08-04T04:29:45.000000Z lpd
Ensures that errordict has at least one empty entry, for the sake of some
astonishingly bad PostScript code that tests for this and has a bug in the
case where it isn't true.
[lib/gs_init.ps]
2000-08-03T20:47:48.000000Z lpd
Improves the smoothness of ShadingType 4 - 7 gradient fills.
[src/gxshade4.c src/gxshade6.c]
2000-08-03T17:42:52.000000Z lpd
Fix: The dependency on gsparamx.$(OBJ) was incorrectly attached to
pdfwrite.dev rather than psdf.dev.
[src/devs.mak]
2000-08-03T06:45:25.000000Z lpd
Fix: The documented limit on the length of a file name was incorrect.
[doc/Language.htm]
2000-08-03T06:43:17.000000Z lpd
Fix: Errors while executing gs_init.ps and other PostScript initialization
files were sometimes ignored, leading to mysterious error messages later.
[src/imainarg.c]
2000-07-29T05:58:28.000000Z lpd
Adds the ability to load CIDFont resources from CFF OpenType font files.
[lib/gs_cff.ps lib/gs_cidfn.ps]
2000-07-29T04:00:00.000000Z lpd
Adds a partially implemented driver that just produces a trace of its
drawing calls. This driver also serves as a minimal example of how to
implement the high-level driver operations.
[src/lib.mak src/gdevtrac.c doc/Drivers.htm]
2000-07-27T14:18:11.000000Z lpd
Fix: 'show'ing an empty string could cause the next string to be positioned
incorrectly.
[src/gdevpdft.c]
2000-07-27T04:19:24.000000Z lpd
Adds glyphs_used to FontDescriptors and pfd to std_fonts in the device
structure. WORK IN PROGRESS.
Updates font embedding code to handle CIDFontType 2 fonts. NOT TESTED.
[src/gdevpdfe.c]
2000-07-24T18:08:38.000000Z lpd
Fix: Type 1 or Type 2 fonts with invalid LanguageGroup values < 0 caused an
error. (Such fonts are invalid, but some real fonts have garbage
LanguageGroup values, and Adobe software doesn't give an error.)
[src/zfont1.c]
2000-07-24T15:12:21.000000Z lpd
Fix: Some DOS/Windows script files didn't use 'call', so they would
terminate execution prematurely if called from another script file.
Directs users to the Ghostscript home page on the Web for information about
third-party drivers.
[doc/New-user.htm]
2000-07-20T14:49:52.000000Z lpd
Removes the SVG driver from the list of projects, since there is a group
close to completing one (referenced from the Ghostscript home page on the
Web).
[doc/Projects.htm]
2000-07-20T01:40:50.000000Z lpd
Fix: When NOPROMPT was set, no flush or flushpage occurred at the end of a
page. (fix from an anonymous user on SourceForge)
[lib/gs_init.ps]
2000-07-19T22:50:18.000000Z lpd
Adds a project for making Ghostscript work as a Netscape browser plug-in.
[doc/Projects.htm]
2000-07-19T21:32:12.000000Z lpd
Fix: Freeing a locking allocator could cause infinite recursion.
[src/gsmemlok.c]
2000-07-19T15:57:54.000000Z lpd
Fix: As a result of some recent changes to fix other problems, setting
certain text state parameters (Tf, Ts, Tz) outside of text mode (BT/ET)
caused an error.
[lib/pdf_ops.ps]
2000-07-19T14:32:00.000000Z lpd
Fix: During compilation, GLSRCDIR was searched before GLGENDIR. (We're very
surprised that this didn't cause detectable trouble before.)
[src/lib.mak]
2000-07-19T14:30:46.000000Z lpd
Fix: The use of macros within procedure argument lists confused ansi2knr.
[src/gximage3.c src/gximage3.h]
2000-07-19T08:12:41.000000Z lpd
Fix: When loading a TrueType font, invalid glyph numbers in the 'post' table
(which appear in some Adobe-created PDF files) caused an error instead of
being ignored; a test was backwards, causing some embedded TrueType fonts in
PDF files to produce a rangecheck error.
[lib/gs_ttf.ps]
2000-07-19T08:11:15.000000Z lpd
Fix: TrueType font loading now requires the Adobe glyph list, but this
dependency was missing from the makefile.
[src/int.mak]
2000-07-18T15:41:55.000000Z lpd
Fix: (correction) An interruption (including a callout for a procedure-based
stream), not a garbage collection, while scanning a binary token sequence
could cause a syntaxerror or corrupted data.
[src/iscan.c]
2000-07-18T15:39:02.000000Z lpd
Fix: A garbage collection occurring while scanning a binary token sequence
could cause a syntaxerror or corrupted data.
[src/iscan.c]
2000-07-17T20:13:03.000000Z lpd
Clarifies that device parameters set with -d or -s can be changed
subsequently.
[doc/Use.htm]

Adds documentation and a script for preparing GNU releases from Aladdin

[doc/Release.htm toolbin/makegnu.tcl]
2000-07-15T19:23:45.000000Z lpd
Updates the (user-contributed) all-architecture build script to work around
a detail in the SGI IRIX C library header files.
[src/all-arch.mak]
2000-07-14T05:30:19.000000Z lpd
Fix: Piped input beginning with a % caused an ioerror. (bug introduced in
6.22)
[lib/pdf_main.ps src/zfileio.c]
2000-07-14T05:28:56.000000Z lpd
Fix: A garbage collection occurring within a save could cause a memory
access error. (bug introduced in 6.22)
[src/zcontext.c]
2000-07-13T02:09:21.000000Z lpd
Fix: Type 2 fonts that used the 'hflex' operator could produce distorted
characters (e.g., slanted bottoms).
[src/gstype2.c]
2000-07-13T02:02:09.000000Z lpd
Fix: A file had accidentally acquired an incorrect license notice.
[src/gscoord.c]
2000-07-12T14:02:04.000000Z lpd
Fix: With some high-level drivers, changing the OutputFile after opening the
device could cause a crash. After the fix, doing this works properly if no
pages have actually been written out, but causes a rangecheck error if any
pages have been written. (This is required to maintain internal
consistency.)
[doc/News.htm src/gdevvec.c]
2000-07-12T04:49:44.000000Z lpd
Removes a structure member no longer needed after a recent fix.
[src/gscoord.c src/gxmatrix.h]
2000-07-11T15:33:19.000000Z lpd
Adds some user-contributed comments about using the Canon BJ200 driver with
the BJ300.
[src/gdevbj10.c src/contrib.mak]
2000-07-11T14:33:54.000000Z lpd
Fix: The word and character spacing values were not tracked correctly when
mixing text and graphics, sometimes producing horizontally misplaced text.
Fix: If the current color space was DeviceRGB, gs_currentgray returned the
wrong value. (bug introduced in 6.22)
[src/gscolor.c]
2000-07-11T09:25:46.000000Z lpd
Fix: Some coordinate computations for Type 1 fonts could lose far too much
precision if _fixed_shift was reduced.
[src/gscoord.c src/gxmatrix.h]
2000-07-10T23:56:55.000000Z lpd
Fix: Local GC in a multi-context system caused a crash. Also updates all the
internal type names in zcontext.c by adding a _t suffix if necessary.
[src/zcontext.c doc/News.htm]
2000-07-10T19:32:59.000000Z lpd
Updates a couple of release procedures.

Adds _simple_final structure type definition macros.
[src/gsstruct.h]
2000-07-10T13:35:24.000000Z lpd
Fix: Redefining setcolorspace could cause an infinite recursion.
[lib/gs_lev2.ps]
2000-07-10T13:18:28.000000Z lpd
Fix: If a badly-constructed PDF file referenced one of the 12 base
alphabetic fonts explicitly as a TrueType font (e.g., /BaseFont
/TimesNewRoman /Subtype /TrueType) without embedding it, the substituted
Type 1 font had the wrong Encoding.
[lib/pdf_font.ps]
2000-07-10T12:48:54.000000Z lpd
Fix: The workaround for attempting to set a 4-element PageSize value in a
page device sometimes caused an error. (bug introduced in 6.21)
[lib/gs_setpd.ps]
2000-07-09T23:29:25.000000Z lpd
Updates the references to the Computer Modern Fontmap on CTAN.
[doc/Fonts.htm doc/New-user.htm]
2000-07-09T23:19:59.000000Z lpd
Fix: $(GLGEN)/md5.h wasn't deleted after compilation.
[src/lib.mak]
2000-07-09T23:11:31.000000Z lpd
Fix: M_2PI was predefined on some systems.
[src/gdevpdfg.c]
2000-07-09T23:10:58.000000Z lpd
Fix: A constant 1 should have been 1L, causing a warning on systems where
sizeof(long) > sizeof(int).
[src/zarith.c]
2000-07-09T22:34:30.000000Z lpd
Fix: Removes the '?' procedure, which was defined solely for the convenience
of users who don't read the documentation and which interfered with the
operation of some code produced by the Adobe PS5 Windows driver.
[lib/gs_init.ps]
2000-07-09T21:09:51.000000Z lpd
Fix: An invalid file name or pattern passed to filenameforall would
(incorrectly) return an empty string rather than not returning any file
names at all.
[src/gp_vms.c]
2000-07-09T21:04:25.000000Z lpd
Adds a little more tracing output for images.
[src/gxidata.c]
2000-07-06T05:29:46.000000Z lpd
Implements finish_copydevice for X windows, to allow copying instances as
well as the prototype.
[src/gdevx.c src/gdevxini.c src/gdevx.h]
2000-07-06T04:13:24.000000Z lpd
Adds a finish_copydevice device procedure, for cleaning up after copying the
bits of a device prototype or instance. For safety, the default
implementation only allows copying the prototype, not instances. This is a
NON-BACKWARD-COMPATIBLE change; however, using copydevice on a device
instance never worked reliably, so it should not have been used this way
before.
Redefines [gs_]copydevice in terms of a new gs_copydevice2/.copydevice2,
which adds a Boolean keep_open argument that requests (but does not
guarantee) that a copy of an open device remain open.
Fix: The "smoke test" procedure for fileset releases didn't stress the
banding code nearly as hard as intended.
[doc/Release.htm]
2000-07-05T04:49:11.000000Z lpd
Adds a findprotodevice "operator", to find a device prototype by name.
[doc/Language.htm lib/gs_init.ps]
2000-07-05T00:48:21.000000Z lpd
Finishes working around the fact that Microsoft C, in defiance of multiple
standards, by default doesn't define the O_ flags for 'open' in fcntl.h (or
anywhere else).
Improves the documentation of copydevice regarding where it allocates the
copy, and documents finddevice.
[doc/Drivers.htm doc/Language.htm]
2000-06-29T23:31:14.000000Z lpd
Fix: The code for registering compiled fonts was sensitive to its position
in the order of loading the initialization files (caused an error if loaded
too early).
[lib/gs_ccfnt.ps]
2000-06-29T16:00:48.000000Z lpd
Brings the language documentation (more) up to date.
[doc/Language.htm]
2000-06-29T15:58:24.000000Z lpd
Changes the name of the unread operator to .unread, retaining unread as a
synonym for backward compatibility.
[src/zfileio.c lib/gs_init.ps]
2000-06-29T15:55:13.000000Z lpd
Fix: If PDF interpretation was included in the build, the very first line of
a non-PDF file wouldn't be processed (if applicable) as a comment.
[lib/pdf_main.ps]
2000-06-28T20:17:00.000000Z lpd
Finishes implementing the Process[DSC]Comment callout.
Fix: In some cases, two successive DSC comments produced a syntaxerror.
[src/ztoken.c]
2000-06-28T05:13:19.000000Z lpd
Fix: Uncolored Patterns used with a gray color produced incorrect PDF
output. (Bug introduced in 6.2x.)
[src/gdevpsdu.c]
2000-06-28T01:36:30.000000Z lpd
Fix: The built-in Identity CMaps had an incorrect entry count for
begincodespacerange and begincidrange; these CMaps, and all Type 0 fonts,
were constructed in a way that was incompatible with some old Adobe font
loading software.
[lib/pdf_font.ps]
2000-06-28T00:47:05.000000Z lpd
Fix: Calling out to process a comment during scanning left an extra element
on the operand stack if the comment appeared within { }.
[src/ztoken.c]
2000-06-27T17:56:04.000000Z lpd
Fix: The change in parameter type checking required for the new
Process[DSC]Comment user parameters broke type checking for system
parameters.
[lib/gs_lev2.ps]
2000-06-27T17:55:05.000000Z lpd
Fix: The dictionary used to hold Encodings wasn't large enough.
[lib/gs_init.ps]
2000-06-27T17:36:42.000000Z lpd
Fix: The makefiles didn't include the requirement that gs_mro_e.ps be loaded
before gs_mgl_e.ps.
[src/int.mak src/devs.mak]
2000-06-27T17:23:13.000000Z lpd
Fix: The makefile missed a dependency (CIDFontType 0 fonts require FontType
2 fonts).
[src/int.mak]
2000-06-27T17:06:32.000000Z lpd
Refactors some PDF-writing code for use in a PDF decompressor.
[lib/pdfwrite.ps]
2000-06-27T14:03:29.000000Z lpd
Adds a reference to a user-maintained Czech translation of the Ghostscript
'man' pages.
[doc/Readme.htm]
2000-06-27T06:32:03.000000Z lpd
Fix: Images that ended prematurely still (again?) weren't written correctly.
[src/gdevpdfj.c]
2000-06-27T00:53:38.000000Z lpd
Adds user parameters ProcessComment and ProcessDSCComment. If not null,
these procedures are called with the file and the comment line whenever the
scanner detects a comment (or non-DSC comment) or DSC comment. NOTE: the
interpreter is currently patched so that ProcessComment is never called.
Fix: Works around a bug in the MSVC++ 5.0 compiler that treats (int <<
unsigned) as unsigned rather than int.
[src/gdevdj9.c src/gdevcd8.c src/gdevcdj.c]
2000-06-19T22:22:51.000000Z lpd
Fix: If the new value of a device parameter was an array with some integers
and some reals, and the first element was a real, a typecheck error would
occur.
[src/iparam.c]
2000-06-13T20:27:26.000000Z lpd
Adds an umbrella document for maintenance procedures, initially describing
the procedure for uploading bug report test data to SourceForge.
[doc/Readme.htm doc/Maintain.htm]
2000-06-13T16:34:42.000000Z lpd
Fix: Text in Type 3 synthesized fonts was often positioned incorrectly,
usually too far to the left. (bug introduced since 6.01)
[src/gdevpdft.c]
2000-06-13T07:05:21.000000Z lpd
Fix: the row buffers for images weren't allocated with a stable allocator,
possibly causing data corruption or invalid accesses if a PostScript program
invoked save/restore within the data-reading procedure for an image.
[src/gsimage.c]
2000-06-13T07:04:18.000000Z lpd
Fix: When allocator debugging was enabled (-Z@), 'restore' didn't clear
vacated space in inner chunks.
[src/gsalloc.c]
2000-06-12T21:45:19.000000Z lpd
Fix: Axial shadings with a non-orthogonal CTM could fail to fill the
required region. (fix from Artifex)
[src/gxshade1.c]
2000-06-12T19:17:03.000000Z lpd
Fix: The code for keeping the Install procedure from getting more and more
deeply nested didn't actually work, and also caused pages with a non-zero
MediaBox offset to be translated incorrectly.
[lib/pdf_main.ps]

Fix: Embedded Type 1 (but not Type 2 / 1C) fonts were written without eexec
encryption. We can't figure out how this happened, because the PDF spec
requires eexec encryption and the correct code was commented out; we suppose
this was a debugging or testing modification that got left in. (bug
introduced since 6.01)

2000-06-12T18:13:51.000000Z lpd
Fix: Works around the fact that Acrobat Reader won't accept /MMType1 fonts,

Fix: Indexed color spaces used in in-line images were being written
incorrectly. Also optimizes Indexed images by converting RGB palettes to
Gray if all the entries are actually gray.

Fix: The elimination of stdin/out/err also eliminated some #defines that are
needed for error printout.
[src/gsio.h]
2000-04-20T23:50:20.000000Z lpd
Adds an essential new file overlooked in the removal of references to
stdin/out/err.
[src/gxstdio.h]
2000-04-20T23:49:40.000000Z lpd
Fix: When pdfwrite was producing PDF 1.3 output, the base 14 fonts were
never embedded, rather than being handled like all other fonts.
[doc/News.htm src/gdevpdff.c]
2000-04-20T23:30:22.000000Z lpd
Removes all remaining direct references to stdin/out/err from the library,

Checks in a file overlooked in the elimination of the gp_ console procedures.
[src/gp_os2.c]
2000-04-20T22:47:35.000000Z lpd
Removes the gp_ procedures for managing screen swapping between console and

Fix: When processing a PDF file, the font substitution heuristic based on
the FontName sometimes overrode the Flags information in the FontDescriptor.
[lib/pdf_font.ps doc/News.htm lib/gs_fonts.ps]
2000-04-20T06:24:39.000000Z lpd
Fix: The fix to make setpagedevice ignore 4-element PageSizes in
InputAttributes was broken. (It's impossible that it could ever have
worked, despite the fact that we tested it.)
[lib/gs_setpd.ps]
2000-04-19T21:37:47.000000Z lpd
Adds a project for creating an OutputDevice resource instance for each
device.
[doc/Projects.htm]
2000-04-19T13:48:48.000000Z lpd
Fix: When choosing a substituted font, 'Serif' had priority over 'Sans', so
unknown fonts with 'SansSerif' in their name would have a serif font
substituted.
[lib/gs_fonts.ps]
2000-04-19T06:01:19.000000Z lpd
Fix: Attempting to set a PageSize with 4 elements actually set the PageSize
(to the first 2 elements), rather than ignoring the attempt. (This is just
a patch to prevent some PageMaker files from being thrown off by the
4-element PageSizes in Input Attributes.)
[lib/gs_setpd.ps]
2000-04-19T05:59:05.000000Z lpd
Fix: putdeviceparams allowed a PageSize or .MediaSize value with the wrong

Increases the VMThreshold when converting PostScript to PDF, to reduce
garbage collection overhead.

2000-04-16T07:48:23.000000Z lpd
Makes undefined XObject resources for the Do operator produce a warning
rather than an error, to parallel Acrobat Reader.
Fix: pdfwrite output could contain commands to set the line width to a

[src/gdevpdfd.c]
2000-04-12T19:25:56.000000Z lpd
Fix: The pdfwrite driver sometimes compressed images in an Indexed color
space with the DCTEncode filter, producing garbage.

2000-04-12T18:44:35.000000Z lpd
In pdfwrite, rewrites the image writing code to use Cos objects rather than
direct printing, and splits off the creation of image dictionaries into a
new file; adds support for tiling with uncolored Patterns; implements
converting ImageType 4 images to their PDF 1.3 counterpart; starts to do the
same for ImageType 3. This code is "in progress" and likely to have
problems for a while.
Makes the second argument of the pfbtopfa script optional, so 'pfbtopfa
dir/x.pfb' is equivalent to 'pfbtopfa dir/x.pfb x.pfa'.
[lib/pfbtopfa man/pfbtopfa.1]

2000-04-11T19:20:56.000000Z lpd
Integrates a couple of minor overlooked changes in the text-writing code.
[src/gdevpdfx.h src/gdevpdf.c src/gdevpdft.c]
2000-04-11T19:10:13.000000Z lpd
Splits off creation and writing of color spaces, and writing color values,
into a separate file. Adds support for (Function-based) Separation and
DeviceN color spaces, general Pattern color spaces, and procedure-based
Indexed color spaces. Adds some code to support Pattern colors, but stubs
it out because it depends on changes in the image writing code that haven't
been integrated yet. In fact, most of the new code isn't called yet,
either.
Implements additional distiller parameters: PreserveHalftoneInfo,
PreserveOverprintSetting, TransferFunctionInfo (except for Apply
vs. Remove), UCRandBGInfo. Splits off graphics state management into
separate files. Implements the remaining graphics state parameters
(halftone, transfer function, black generation, undercolor removal, halftone
phase, smoothness, overprint, stroke adjustment) ****** EXCEPT FOR IMAGES
******. In anticipation of handling more general colors, renames
pdf_set_color as pdf_set_pure_color, and adds pdf_set_drawing_color.
Adds ExtGState resources. These should be written and freed at the end of
each page, but they aren't yet.
[src/gdevpdfx.h]
2000-04-11T16:32:51.000000Z lpd
Fix: If a font didn't have a FontName (which is the case for bitmap fonts
produced by recent versions of dvips), ps2epsi caused an error.
[lib/ps2epsi.ps]
2000-04-11T16:06:57.000000Z lpd
Factors out code for writing functions and for adding filter-related entries

Fix: Embedded subset CFF fonts in PDF files were defined using the name in

[lib/gs_cff.ps lib/pdf_ops.ps]
2000-04-10T19:39:44.000000Z lpd
Makes Separation and DeviceN color spaces detect that their tint transform

Fix: gsmisc.c didn't compile in DEBUG mode on systems with a non-standard
prototype for the sqrt function.
[src/gsmisc.c]
2000-04-10T07:48:37.000000Z lpd
Overhauls font embedding in the PDF writer: splits off the code into a new
file (gdevpdfe.c), writes embedded Type 1 fonts as Type 1C (CFF Type 2), and
adds a little bit of code for future support of Type 0 and CID-keyed fonts.
Fix: Writing a Type 2 CFF with multiply-encoded glyphs produced an incorrect
Encoding. Also, when producing output for PDF 1.2 files, no longer emits
certain opcodes that cause an (unjustified) error in Acrobat Reader 3 for
Linux.

Completely redesigns the representation of CMaps, to reduce space
requirements and make comparing them more reasonable, changing gs_cmap to
gs_cmap_t and gx_code_map to gx_code_map_t. (****** NOTE ****** The

Extends the undocumented CCRun procedure to take an additional argument, a
Private dictionary, required by some Adobe font downloading code.
[lib/gs_type1.ps]
2000-04-06T04:50:28.000000Z lpd
Fix: Some Adobe font downloading code assumed that loading a resource file
would never leave extra values on the stack; our implementation didn't
ensure this (by popping them if needed).
[lib/gs_res.ps]

Implements the framework for superexec (but none of the actual access check

Fix: The implementation of resourcestatus wasn't compatible with some badly
written code in an Adobe font downloader that assumes that the
implementation of resourcestatus in Generic and Font is the same.
[lib/gs_res.ps]
2000-04-05T21:07:02.000000Z lpd
Fix: resourceforall didn't enumerate external (loadable) instances, and

[src/.cvsignore src .cvsignore /trunk/gs]
2000-04-04T22:26:02.000000Z lpd
Fixes several problems in resourceforall and resource loading: the operands
of resourceforall were restored even in the case of an error in the client's
procedure; the name Instances had special meaning for some Adobe code;
resourceforall caused an invalidaccess error if an operand was in local VM
but the current VM was global; loading a resource from a file could cause a
typecheck error if the file left values on the operand stack.
Fix: When printing on monochrome LaserJet/DeskJet printers, the driver
didn't set the number of copies to 1; on the LJ 4si, this sometimes caused
double printing.
[src/gdevdjet.c]
2000-04-03T06:01:25.000000Z lpd
Fix: Resolving a Shading didn't create a reusable stream for the shading
data; since the data was then read at unpredictable times, the shading or
other constructs in the PDF file could read incorrect data.
[lib/pdf_draw.ps]
2000-04-03T02:54:41.000000Z lpd
Implements the AutoRotatePages distiller parameter.

Adds a variety of tools used to build and distribute Ghostscript releases.
The only documentation is comments in the files themselves, and there isn't
much of it. All aspects of these tools are subject to change without

2000-03-30T07:03:59.000000Z lpd
Fix: Filling or clipping with ridiculously large (out-of-bounds) coordinates

probably not the last such bug.)
[src/gxfill.c]

Fixes a couple of typos in the recently checked-in image interpolation fix.
[src/siscale.c]
2000-03-29T22:10:31.000000Z lpd
Changes the procs structure of gs_type1_data to an in-line structure rather
than a pointer to a const structure. (Needed for moving CIDFontType 0
support into C.)
Fix: When FPU_TYPE <= 0, the image interpolation code lost too much
accuracy, producing color streaks in the output. (Fix by DanCoby.)
[src/siscale.c]
2000-03-29T19:29:08.000000Z lpd
Adds a note about bogus "ANSI aliasing" warnings from the DEC C compiler.

Fix: The PCL XL 2.0 value for sRGB color space was wrong, and the attribute
for writing mode was missing.
[src/gdevpxen.h src/gdevpxat.h]
2000-03-28T18:47:02.000000Z lpd
Changes the get_outline / glyph_data procedure for getting encoded font
outline data to return an indication of whether the outline data were just
allocated and can be freed by the client. (This is a possibly
non-backward-compatible change.)
Fix: Re-registering a CIDFont with definefont, or defining a CIDFont with
definefont instead of /CIDFont defineresource, caused an invalidfont error
or a crash.
[lib/gs_fonts.ps lib/gs_cidfn.ps]
2000-03-28T18:20:39.000000Z lpd
Fix: In some cases, re-registering an existing font or CIDFont with

Changes the default value of FPU_TYPE in all Windows and OS/2 makefiles from

[src/spsdf.c src/gdevpdfr.c src/gxclpath.c]
2000-03-28T00:52:46.000000Z lpd
Fix: In the output of the pswrite driver (pdf2ps, ps2ps), the showpage for
each page occurred before, not after, the restore that ended the page
contents. This contradicted Adobe's documentation, and made utilities like
N-up printing not work properly.
[src/gdevps.c]
2000-03-27T16:36:24.000000Z lpd
Changes the implementation of incrementally loaded CIDFontType 0 fonts to

[src/gdevpdfm.c]
2000-03-24T06:12:52.000000Z lpd
Substantially enhances the Cos object machinery. Interface: Adds a few more
procedures, including a procedure to create a stream that writes directly
into a Cos stream object, procedures for putting more kinds of values into
arrays and dictionaries, and a param_list interface. Changes Cos objects to
store a reference to the PDF device, and removes the device argument from
all Cos procedures other than object creation. Replaces the Boolean
is_object member of Cos values by a value_type enum: clients must now use
COS_VALUE_IS_OBJECT() to test whether a value is an object reference. To
reduce allocator overhead, makes the Cos procedures that take C strings no
longer copy the string. Records whether each Cos object has been written
into the output, so that in the future (but not in this batch of changes)
resource definitions can be copied at the end of each page. Implementation:
Moves more of the implementation of Cos objects to the .c file.
Changes the new .filename operator to return true/false rather than causing
an error; redefines findlibfile in terms of a simpler .libfile operator +
.filename.
[src/zfileio.c src/zfile.c lib/gs_init.ps]
2000-03-23T18:31:46.000000Z lpd
Fix: The "fix" for FunctionTypes 2 and 3 in PDF files had made things worse,
because the code didn't distinguish between resolving to a PostScript

Fixes a bug in the mswinpr2 driver in the handling of BitsPerPixel.
[src/gdevwpr2.c]
2000-03-21T23:08:32.000000Z lpd
Fix: In PDF files, the page CropBox was not being used to clip the output.
[lib/pdf_main.ps doc/News.htm lib/pdf_ops.ps]
2000-03-21T21:34:57.000000Z lpd
Splits off the ReusableStreamDecode filter as a separate module, since
CIDFontType 0 fonts will use it even in LanguageLevels below 3.
Changes Subr loading for CIDFontType 0 fonts from lazy to immediate, so that
C code can be guaranteed access to the Subrs. (In every CIDFontType 0 font
that we have seen, SubrCount is 5, so this has no significant time or space
cost.) Also adds support for FDBytes > 1 in GlyphDirectory definitions.
[lib/gs_cidfn.ps]
2000-03-21T18:36:36.000000Z lpd
Fix: When ProcessColorModel=/DeviceCMYK, if the first object on a page or
after changing the clipping path was white, the PDF writer would write it as
black.
[src/gdevpdfu.c]
2000-03-21T17:01:33.000000Z lpd
Adds invocation scripts and documentation for the PDF "optimizer".
Extends the C support for CIDFontType 0 fonts to include those with FontType
2 subfonts in the FDArray (an Adobe 3011 addition, specifically for CFF
fonts).
Replaces the O(N^2) sorting algorithm for printing unencoded characters with
a O(N log N) algorithm, which makes printing Unicode and Chinese/Japanese
fonts practical.
[lib/prfont.ps]
2000-03-21T00:43:17.000000Z lpd
Fix: The test for whether an CIDFontType 2 outline string was large enough
to include prefixed metrics was backwards, which would have caused problems
with any font that used MetricsCount.
[src/zfcid.c]
2000-03-21T00:32:15.000000Z lpd
Hooks the new CIDMap code into the BuildGlyph procedure for CIDFontType 2
fonts. (Contrary to a previous log comment, MetricsCount is already hooked
in.) Support for CIDFontType 2 fonts is now implemented entirely in C, as
for Type 42 fonts.
[src/zfcid.c lib/gs_cidfn.ps]
2000-03-21T00:11:55.000000Z lpd
Fix: The addition of the dummy cid_Setup procedure in gs 6.01 was
accidentally commented out.
[lib/gs_cidfn.ps]
2000-03-20T21:05:11.000000Z lpd
Fix: The color_info member of the Windows and OS/2 printer devices (and
other devices using PC-style palettes) wasn't initialized properly, causing
improper behavior.
[src/gdevpccm.h src/gdevwpr2.c src/gdevos2p.c]
2000-03-20T20:04:20.000000Z lpd
Notes that the argument list for the internal build_gs_TrueType_font
procedure has changed, as part of the CIDFont migration to C code.
[doc/News.htm]
2000-03-20T19:53:06.000000Z lpd
Starts to move support for CIDFontType 0 and 2 into C code, needed by the
PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for
CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts
that have a GlyphDirectory (not documented in the PLRM, but clearly
correct). Implements Adobe 3011 features: integer and dictionary CIDMaps,
and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code,
which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.)
Updates the makefile for the renaming of gdevpsdf.c => gdevpsdu.c.
[src/devs.mak]
2000-03-20T19:03:43.000000Z lpd
Renames an inappropriately named file.

Updates dependencies to reflect today's batches of checked-in changes.
[src/lib.mak src/int.mak src/devs.mak]
2000-03-20T07:02:12.000000Z lpd
Moves font-writing support into a new module (gdevpsf*), changing the source
file names. Adds the ability to write CFF fonts, with either Type 1 or Type
2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts
with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to
Type 2, including optimizing sequences of Type 1 operators into a single
Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT
TESTED]. Starts (just barely) to remove more unneeded information from
embedded TrueType fonts.
Starts to move support for CIDFontType 0 and 2 fonts into C code. (These
header files are the ones needed to compile the new gdevpsf* files; they
don't interact with any existing code.)
[src/gxcid.h src/gxfcid.h]
2000-03-20T05:58:15.000000Z lpd
Fix: The computation for testing whether a tiled pattern could be
represented in line, and whether it exceeded Acrobat Reader's size limit,
was wrong, causing some patterns not to be represented as Patterns.
[src/gdevpdfi.c]
2000-03-20T05:54:13.000000Z lpd
Fix: The pointer enumeration procedure for pdf_image_enum was wrong,
possibly producing a mangled pointer and a memory access error if a garbage
collection occured while writing an image in a PDF file.
[src/gdevpdfi.c]
2000-03-20T05:40:04.000000Z lpd
Adds parsing for the remaining Acrobat Distiller 4 parameters. Implements
the LockDistillerParams, xxxDownsampleThreshold, xxxImageDict, and
xxxACSImageDict distiller parameters. Implements DCTEncode as an
xxxImageFilter option (it used to cause a crash). Makes the
AutoFilterxxxImages distiller parameters select JPEG encoding (with ACSDict)
if the image has 8 bits per component and is not Indexed, and LZW/Flate
otherwise: this still isn't right, but it's closer. Implementation changes:
Changes the implementation of distiller parameter dictionaries from stream
states to parameter lists; changes the test for masks in
psdf_setup_image_filters, and changes the image argument from gs_image_t to
gs_pixel_image_t.
Adds a PDF linearizer ("optimizer"). This is a separate utility (not
integrated with the pdfwrite driver), written in PostScript.
[lib/pdfwrite.ps doc/Psfiles.htm lib/pdfopt.ps]
2000-03-20T04:30:49.000000Z lpd
Adds a .fileposition operator that will read the position even of
non-positionable streams, needed for the PDF linearizer.
[src/zfileio.c]
2000-03-19T18:46:44.000000Z lpd
Exports the 'blend' operators of the Type 1 interpreter, for use by the Type
1 / Type 2 font writer.
[src/gstype1.c src/gxtype1.c src/gxtype1.h]

[doc/Changes.htm src/version.mak]
2000-03-19T17:26:42.000000Z lpd
Refactors some code to make it usable by the PDF linearizer.
[lib/pdf_main.ps]
2000-03-19T17:21:36.000000Z lpd
Fix: Separation color spaces didn't store the separation name.
[src/zcssepr.c]
2000-03-19T17:14:47.000000Z lpd
Fix: If log2_transfer_map_size > 8, identity transfer functions returned
garbage. The fix requires that if a client wants to set a transfer function
to the identity mapping, it must call gx_set_identity_transfer rather than
simply setting the procedure to gs_identity_transfer.
Adds procedures for building and accessing DeviceN color spaces.
[src/gscdevn.h src/gscdevn.c]
2000-03-19T16:53:50.000000Z lpd
Fix: .buildfont0 should not check CIDSystemInfo compatibility. The PLRM3
says PostScript interpreters do not make this check, even though the PLRM2
says compatibility is required (!).
[src/zfcmap.c]
2000-03-19T16:45:47.000000Z lpd
Refactors the code for building fonts so it can be used for FDArray entries
of CIDFontType 0 fonts.
[src/bfont.h src/zbfont.c]
2000-03-19T16:37:28.000000Z lpd
Makes st_indexed_map private. Clients must now use the constructor
procedure alloc_indexed_map rather than allocating instances directly.
Adds a proc_data member to the map for Separation and Indexed color spaces.
[src/gxcolor2.h src/gscolor2.c]
2000-03-19T15:47:47.000000Z lpd
Documents the fact that drivers that device halftone order implementations
must now provide the new bit_index procedure. (This should have been
documented when bit_index was introduced!)
[doc/News.htm]
2000-03-19T15:43:36.000000Z lpd
Records the CTM used for sampling HalftoneType 1 spot functions. This is
needed for recognizing the standard spot functions when producing PDF
output. Also factors the code for initializing spot functions for the
benefit of the PDF writer.
[src/gshtscr.c src/gzht.h src/gxdht.h]
2000-03-19T15:35:31.000000Z lpd
Adds a procedure for copying one parameter list to another.
[src/gsparamx.c src/gsparamx.h]
2000-03-19T15:28:34.000000Z lpd
Makes Separation and DeviceN color spaces convert their tint transform
function to a FunctionType 4 Function if possible, for better accuracy and
to allow writing in PDF files.
[lib/gs_lev2.ps lib/gs_ll3.ps]
2000-03-19T15:23:10.000000Z lpd
Fix: FunctionType 2 and 3 functions didn't work.
[lib/pdf_draw.ps]
2000-03-19T15:16:11.000000Z lpd
Changes the key type returned by parameter list enumeration to include a
persistence flag, makes C parameter lists support non-persistent keys, and
upgrades GC descriptors so that parameter lists can be used non-transiently;
updates implementors of parameter lists to call gs_param_list_init to
initialize the common members, which is now required.
Fix: Enumerating the elements of a dictionary-based parameter list returned
garbage for the keys.
[src/iparam.c]
2000-03-19T15:07:59.000000Z lpd
Undoes a premature change that depends on an update not yet checked in.
[src/gscparam.c]
2000-03-19T15:00:05.000000Z lpd
Adds a procedure for allocating a C parameter list.
[src/gscparam.c src/gsparam.h]
2000-03-19T07:37:03.000000Z lpd
Fix: the PDF interpreter hadn't been updated for the move to library-based
FunctionType 4 Functions, and still tried to bind the names true and false
to the no longer existing operators .true and .false.
[lib/pdf_draw.ps]
2000-03-19T07:33:08.000000Z lpd
Splits off "vanilla" Functions into separate files, in anticipation of
removing them (they were only used to implement PostScript Calculator
Functions).
Adds virtual procedures for Functions to write their parameters to a
parameter list, and to access their data source and subfunctions. This is
needed for writing Functions in PDF files. This change is also a
prerequisite for the C implemention of FunctionType 4 functions, even though
it appears later in the change log.
Adds dependencies for the new implementation of FunctionType 4 functions.
[src/int.mak]
2000-03-19T06:56:23.000000Z lpd
Replaces the implementation of FunctionType 4 functions at the PostScript
language level with one that uses the new library-based facilities.
[src/zfunc4.c src/zdevice2.c]
2000-03-19T06:51:13.000000Z lpd
Changes the default value of BufferSpace to 4 Mb. In desktop applications,
this is a reasonable value that can substantially improve performance
(especially for color printers); embedded applications will want to set
BufferSpace themselves in any case.
[doc/News.htm src/gdevprn.h]
2000-03-19T06:46:08.000000Z lpd
Moves gx_device_color_equal to the public API, for detecting redundant color
setting when writing PDF files.
[src/gsdcolor.h src/gxdcolor.c src/gxdcolor.h]
2000-03-19T06:07:15.000000Z lpd
Adds a new document listing projects with which we are seeking help. Also
makes the description of Changes.htm and News.htm more accurate.
Updates makefiles with dependencies for recent changes.
[src/lib.mak src/int.mak]
2000-03-19T05:25:53.000000Z lpd
Reimplements "PostScript calculator" (FunctionType 4) functions entirely in
C, to allow them to be written out in PDF files.
[src/gsfunc4.h src/gsstruct.h src/gsfunc4.c]
2000-03-19T05:20:28.000000Z lpd
Adds a public procedure for getting a palette entry of an Indexed color
space, used when writing Indexed color spaces in PDF files.
[src/gscolor2.h src/gscindex.h src/gscolor2.c]
2000-03-19T05:10:55.000000Z lpd
Adds a bit_index procedure to the implementation of device halftones,
required for writing halftones in PDF files. (The only implementors are
internal ones.)
[src/gxdht.h src/gxhtbit.c]
2000-03-19T05:03:31.000000Z lpd
Fix: The AutoPositionEPSFiles Distiller parameter was misspelled
AutoPositionEPSFile.
[lib/gs_pdfwr.ps]
2000-03-19T04:32:09.000000Z lpd
Documents the fact that ImageType 4 images now cause an error for
out-of-range MaskColor values.
[doc/News.htm]
2000-03-19T04:10:09.000000Z lpd
Fix: ImageType 4 images didn't give an error for out-of-range MaskColor
values. The file also had an unnecessary #include.
[src/gximage4.c]
2000-03-19T04:03:45.000000Z lpd
Fix: The parameters of SubFileDecode filters weren't initialized fully
(required by a change in this version).
[src/zfilter.c]
2000-03-19T03:58:51.000000Z lpd
Fix: TrueType fonts didn't use vhea/vmtx if WMode = 1. Also makes
gs_font_type42 subclassable, for implementing CIDFontType 2 fonts, and makes
its procedure for getting a glyph's side bearing and width virtual, required
to support MetricsCount in CIDFontType 2 fonts.
[src/gxfont42.h src/gstype42.c]
2000-03-19T03:37:08.000000Z lpd
Fix: param_coerce_typed, which works with any parameter list implementation,
was incorrectly described as associated with the default implementation.
[src/gsparam.h]
2000-03-19T03:20:18.000000Z lpd
Adds a skip_count parameter to the SubFileDecode filter, giving the number
of initial bytes or records to skip over. (Needed for printing FunctionType
4 functions, possibly useful for other things.)
[src/sfilter.h src/sfilter1.c]
2000-03-19T03:15:02.000000Z lpd
Fix: s_add_filter didn't ensure enough buffering. This entailed moving the
NullEncode/Decode filters to stream.[hc].
Adds a public procedure for determining whether a PostScript object is a
Function, and if so, returning the pointer to the gs_function_t structure.
[src/zfunc.c src/ifunc.h]
2000-03-19T02:16:58.000000Z lpd
Speeds up Function evaluation slightly, by preallocating space for a
reasonable number of operands and results on the C stack rather than always
allocating it on the heap.
[src/zfunc.c]
2000-03-19T02:12:37.000000Z lpd
Fix: The attribute check for Functions being executed was incorrect (always
succeeded).
[src/zfunc.c]
2000-03-19T02:07:45.000000Z lpd
Refactors the code for getting Type 1/2/4 font parameters so it can be used
for FDArray entries of CIDFontType 0 fonts.
[src/zfont1.c src/ifont1.h]
2000-03-19T02:00:09.000000Z lpd
Fix: pdfread.dev incorrectly depended on dpsnext_.
[src/int.mak]
2000-03-19T01:53:58.000000Z lpd
Changes the PDF interpreter so that following an object reference doesn't
store the result back into the referring slot, and so that # # R always
creates an indirect object. This is necessary for the PDF linearizer. It
shouldn't have any visible effect (other than a possible small performance
cost).
[lib/pdf_base.ps lib/pdf_draw.ps]
2000-03-19T01:50:05.000000Z lpd
Adds a lforall procedure for the PDF linearizer.
[lib/pdf_base.ps]
2000-03-19T01:46:27.000000Z lpd
Fix: PDF images with a Mask ignored the mask.
[lib/pdf_draw.ps]
2000-03-19T01:44:53.000000Z lpd
Fix: PDF images with DeviceN color spaces caused an error.
[lib/pdf_draw.ps]
2000-03-19T01:33:23.000000Z lpd
Fix: EXTEND_NAMES had stopped working, because not all places that needed
the index of a name ref used name_index rather than r_size (ilocate.c), and
because the high_index value in the name sub-table was set incorrectly
(iname.c).
Fix: The CFF reader gave an error if a font included any Subrs (it's very
surprising that this hasn't surfaced before, but apparently Acrobat
Distiller always produces CFF fonts with no Subrs); the CFF reader didn't
default lenIV to -1 for Type 1 CharStrings; the CFF reader wasn't able to
read CIDFonts.
[lib/gs_cff.ps lib/gs_cidfn.ps]
2000-03-19T00:38:50.000000Z lpd
Adds a pseudo-encoding for the CFF StandardStrings that represent
characters.
Increments the version number to 6.20, in anticipation of the next release.
(We do this at the beginning of the development for a release, not the end.)
Fix: In the X driver, the full-page buffer controlled by -dMaxBitmap= wasn't
allocated with a stable allocator, possibly leading to memory access errors
if save/restore were used.
[src/gdevxini.c]
2000-03-18T01:45:16.000000Z lpd
Fix: For printer devices, a non-null definition for OutputFile was required
even on platforms that had a default printer (as implemented by
gp_open_printer for that platform).
Fixes a typo in the fix for putting stdout in binary mode.
[src/gp_ntfs.c]
2000-03-17T17:42:59.000000Z lpd
Adds information on building with the Intel C/C++ optimizing compiler
(requires the Microsoft Visual C++ environment), and fixes a typo in the link to ftp.cdrom.com.
[doc/Make.htm]
2000-03-17T08:17:55.000000Z lpd
Fix: The code for Axial shadings incorrectly assumed that if the shading
axis was horizontal or vertical in user space, it was also horizontal or
vertical in device space: this caused incorrect results when the CTM wasn't
orthogonal.
[src/gxshade1.c]
2000-03-17T07:35:43.000000Z lpd
Fix: The X driver's algorithm for deciding when to update the screen was
changed several times between 5.50 and 6.0, and one of the more recent
changes caused it to copy many more pixels to the screen than necessary if
the file was making marks on the page in widely separated places.
[src/gdevx.c]
2000-03-17T06:22:59.000000Z lpd
On Windows, puts stdout into binary mode as well as stdin, to allow piping
printer output through stdout (not a good idea, but it should be supported
as well as on other platforms).
[src/gp_ntfs.c src/dwmainc.cpp]
2000-03-17T04:40:47.000000Z lpd
Removes the attempted documentation on building Windows executable
distributions: it was never correct, and Aladdin will no longer be creating
such distributions. Also reorganizes the document slightly and brings the
rest of it fully into line with reality.
[doc/Release.htm]
2000-03-17T03:01:58.000000Z lpd
Adds a disclaimer of responsibility for the makefile section for creating
distribution archives, which Aladdin is no longer maintaining.
[src/winint.mak]
2000-03-17T02:59:26.000000Z lpd
Adds a missing dependency of gdevpdft.o on gxfont42.h.
[src/devs.mak]
2000-03-17T00:47:08.000000Z lpd
Updates the version number reference in the troff header.
[man/ps2pdf.1 man/ps2ps.1]
2000-03-16T08:09:42.000000Z lpd
Adds documentation and a makefile entry for Matthew Gelhaus' cdj880 driver.
The code will eventually be included in gdevcd8.c, but it is not yet mature
enough.
[src/contrib.mak doc/Devices.htm]
2000-03-16T07:38:07.000000Z lpd
Fix: Directly-loaded TrueType fonts (including embedded TrueType fonts in
PDF files) could get confused with each other in the cache, because their
XUIDs were based on the font checksum field, which some fonts don't have set
correctly.
[lib/gs_ttf.ps]
2000-03-16T04:05:07.000000Z lpd
Adds a reference to a third-party Fontmap for the Computer Modern fonts.
[doc/Fonts.htm]
2000-03-16T02:03:40.000000Z lpd
Adds two more user-contributed 'uniprint' printer parameter sets: Epson
Stylus Color 640, and a generic Epson Stylus Color in high resolution mode
(720x720 dpi).
[lib/stc640p.upp lib/stcany_h.upp]
2000-03-16T02:01:36.000000Z lpd
Fixes a problem producing too much black in the output; also adds support
for 5 new printers (H-P Color DeskJet 690, H-P DesignJet 750, and Epson
Stylus Color 200). Note that this is user-contributed code.
Adds the ability to set the ProcessColorModel of the pdfwrite device to
/DeviceGray, /DeviceRGB, or /DeviceCMYK. This affects the color space used
for fill, stroke, text, and imagemask, and for images that (for whatever
reason) can't be written in their specified color space. Note that this is
a short-term fix: pdfwrite should output colors in the color space in which
they were specified. However, a proper fix will require more significant
architectural changes.
Adds entries for ibm-rs6000-aix-4.3, sgi-mips-irix6.5-64bit, and
sun-sparc-solaris-64bit.
[src/all-arch.mak]
2000-03-15T07:29:53.000000Z lpd
Adds information on uninstalling Ghostscript on Windows.
[doc/Install.htm]
2000-03-15T07:23:52.000000Z lpd
Fix: The gs###src.zip and gs###lib.zip files weren't mentioned as being
included in distributions; News.htm and Changes.htm weren't mentioned at
all.
[doc/Release.htm]
2000-03-15T02:24:58.000000Z lpd
Revises the release procedures to reflect use of SourceForge, and to
separate out the procedures for building Windows executables.
[doc/Release.htm]
2000-03-14T20:20:20.000000Z lpd
Changes the ps2pdf MS Windows / MS-DOS scripts to use temporary files to
avoid the absurdly low limits on the length of a command line and the total
size of environment variable definitions.
Adds a change log generated mechanically from the CVS logs. Future releases
may omit this file (doc/Changes.htm) from their change log.
[doc/Changes.htm doc/News.htm]
2000-03-14T06:39:23.000000Z lpd
Partially updates the release procedure documentation to reflect the use of
SourceForge and CVS.
[doc/Release.htm]
2000-03-14T06:14:44.000000Z lpd
Moves all history for versions 5.n into History5.htm; creates History6.htm
for versions 6.n; redefines News.htm as containing only news for the current
release; adds (a link to) Changes.htm for the mechanically generated change
log.
Changes the default undercolor removal and black generation functions back
from f(k) = k to f(k) = 0. This fixes some, but not all, of the reported
problems with color inkjet output in 6.0.
[src/gxdcconv.c lib/gs_init.ps]
2000-03-10T17:18:29.000000Z lpd
Updates the version # to 6.01, and the version date.
[lib/gs_init.ps src/version.mak]
2000-03-10T15:55:39.000000Z lpd
Updates the documentation for building Aladdin releases to reflect revised
procedures for the Windows executable, and a few other minor changes.
[doc/Release.htm]
2000-03-10T15:53:08.000000Z lpd
Fix: gsmalloc.c didn't include the prototype for gs_exit(), which it calls.
[src/lib.mak]
2000-03-10T15:48:58.000000Z lpd
Updates all makefiles to the current libpng version, 1.0.5.
Fix: the "all architectures" build and test script hadn't been updated to
use different STDLIBS values depending on where the platform provides the
pthreads library.
[src/all-arch.mak]
2000-03-10T08:18:36.000000Z lpd
Removes a temporary file that was included in the fileset by mistake.
[lib/history]
2000-03-10T08:17:06.000000Z lpd
Fix: The Windows zip archive didn't include font metrics files. (This
change only fixes the build procedure: it doesn't actually update the
currently released zip archive.)
[src/winint.mak]
2000-03-10T08:15:31.000000Z lpd
Fix: The Watcom compiler switches didn't force enums to occupy a full int,
leading to execution errors because the code casts (enum *) pointers to (int
*).
[src/wccommon.mak]
2000-03-10T08:02:59.000000Z lpd
Removes support for VAX C, which DEC stopped supporting 9 (!) years ago.
Fix: The Unix install process tried to make links without deleting them
first.
[src/unixinst.mak]
2000-03-10T07:45:50.000000Z lpd
Enhances the [e]pswrite driver to handle Indexed color spaces over Device
color spaces, only with the standard Decode.
[src/gdevps.c]
2000-03-10T07:44:27.000000Z lpd
Fix: The [e]pswrite driver produced invalid output if the input file didn't
end with a showpage.
Also cleans up some formatting and removes a redundant test.
[src/gdevps.c]
2000-03-10T07:40:00.000000Z lpd
Fix: The ps2pdf*.bat scripts didn't set PS2PDFSW to the empty string if
there were no arguments, causing the same file to be processed again.
[lib/ps2pdf12.bat lib/ps2pdf13.bat]
2000-03-10T07:33:44.000000Z lpd
Updates the Brother HL7xx drivers with a new user-contributed version, plus
a couple of minor fixes.
[src/contrib.mak src/gdevhl7x.c]
2000-03-10T07:32:43.000000Z lpd
Fix: The makefile still referred to a long-gone driver for the DEC LA70.
[src/contrib.mak]
2000-03-10T07:30:54.000000Z lpd
Fix: The dependency list for coslwxl omitted a $(DD).
[src/contrib.mak]
2000-03-10T07:06:08.000000Z lpd
Clarifies when xdpyinfo and xwininfo are needed.
Adds privacy options for problem reports.
[doc/Bug-form.htm]
2000-03-10T07:03:57.000000Z lpd
Removes an inappropriate copying notice.
[doc/Hershey.htm]
2000-03-10T07:03:09.000000Z lpd
Fix: The description of the value returned by code_map_decode_next in *pchr
was incorrect. (documentation bug only)
[src/gsfcmap.c]
2000-03-10T07:02:07.000000Z lpd
Fix: The %ram% IODevice was defined, but should not be (it represents a
RAM-based file system, which Ghostscript does not provide).
Fix: The type of the %null% IODevice was /FileSystem rather than /Special.
[src/int.mak src/ziodev2.c]
2000-03-10T07:00:28.000000Z lpd
Fixes incorrect documentation of several procedures.
[lib/gs_fonts.ps]
2000-03-10T06:56:27.000000Z lpd
Fix: When operating in buffered mode (MaxBitmap > 0), the X driver sometimes
failed to copy all of the updated area to the screen.
Some Adobe CIDFonts include a line
/Setup /cid_Setup load def
that apparently is intended only to prevent the fonts from being loaded by a
standard PostScript interpreter (as opposed to ATM or a special font
loader), since cid_Setup is not defined anywhere and Setup is never
referenced; this change adds a dummy definition of cid_Setup to work around
this.
[lib/gs_cidfn.ps]
2000-03-10T04:41:47.000000Z lpd
Fix: The check for a show within a cshow procedure for a CID font was wrong.
Fix: Character widths in CIDFontType 0 fonts were ignored (!).
Adds a .glyphwidth operator to support correct handling of character widths
for CID fonts.
Adds a glyphwidth procedure to the library, like glyphshow and glyphpath, in
order to support correct handling of widths for CID fonts.
Fix: Images with input from a file or filter demanded 1 byte of data too
many, sometimes causing the last line of the image to be dropped. (bug
probably introduced in 6.0)
[src/zimage.c]
2000-03-10T04:35:53.000000Z lpd
Fix: fileposition didn't give an error for filters or non-seekable streams.
Fix: An incorrectly formatted procedure couldn't be converted correctly by
ansi2knr.
[src/gxidata.c]
2000-03-10T04:29:37.000000Z lpd
Changes a few macro definitions to work around over-zealous compiler
warnings.
[src/gstype1.c src/gstype2.c src/gxtype1.h]
2000-03-10T04:27:31.000000Z lpd
Fix: Writing of dictionaries in binary object output, a non-standard
extension, was enabled by default, and also had to be enabled at startup
time if it was ever going to be used.
Fix: Binary error messages caused an error if the command wasn't of a type
that printobject could handle. We now do what the Adobe implementations
appear to do in this case, namely, convert the object with cvs.
[lib/gs_btokn.ps]
2000-03-10T04:26:07.000000Z lpd
Fix: The mswinpr2 driver didn't handle setting BitsPerPixel to the same
value when the device was already open, possibly causing an error on restore
or grestore.
[src/gdevwpr2.c]
2000-03-10T04:16:09.000000Z lpd
Fix: When converting PostScript to PDF, selecting /Bicubic as an image
DownsampleType caused an error instead of defaulting to /Average.
Fix: The type of the %pipe% IODevice was /FileSystem, whereas it should be
/Special.
[src/gdevpipe.c]
2000-03-10T04:08:23.000000Z lpd
Fix: The prototype for gs_exit() was not included even though gs_exit() was
called.
Fix: A cast discarded const unnecessarily.
[src/gsalloc.c]
2000-03-10T04:06:15.000000Z lpd
Fix: RasterOps with source transparency = 0, texture transparency = 1 didn't
match the (very peculiar) H-P specification even if TRANSPARENCY_PER_H_P was
defined.
[src/gsropt.h src/gdevmrop.h src/gdevdrop.c]
2000-03-10T04:04:38.000000Z lpd
Fix: The code for handling execstackoverflow errors didn't cut back the
stack correctly, possibly causing invalid memory accesses if an incorrect
attempt was made to run a cleanup procedure.
[src/interp.c]
2000-03-10T04:01:55.000000Z lpd
Adds implementations of the devforall, devstatus, and diskonline
compatibility operators.
[lib/gs_statd.ps]
2000-03-10T04:00:45.000000Z lpd
Adds a new example file, a 3-D synthetic image.
[examples/doretree.ps]
2000-03-10T03:58:14.000000Z lpd
Cleans up some formatting.
[lib/pdf_base.ps]
2000-03-10T03:57:50.000000Z lpd
Fix: When interpreting a PDF file, substituted small-cap fonts were created
with incorrect scaling.
[lib/pdf_font.ps]
2000-03-10T03:57:03.000000Z lpd
Fix: When interpreting a PDF file, text drawing operators didn't reset the
text position, so strings could get displayed on top of each other. (bug
introduced by a fix in 5.98)
[lib/pdf_ops.ps]
2000-03-10T03:56:11.000000Z lpd
Fix: When interpreting a PDF file, the Install page device procedure got
more and more deeply nested after every page, eventually causing an
execstackoverflow.
[lib/pdf_main.ps]
2000-03-10T03:48:48.000000Z lpd
Fix: Incrementally downloaded TrueType fonts produced truncated Widths
tables in the output. We have patched this with a ******HACK****** that
causes such fonts to be converted to bitmaps: the correct fix (to delay
determining the range of valid characters until the font is written) is too
large a change to make in a bug fix release.
[src/gdevpdft.c]
2000-03-10T03:48:10.000000Z lpd
Fix: The change in 5.99 to work around Acrobat Reader's 32K limit on user
space coordinates caused all 0-width rectangles to disappear, which had
major effects on some files.
[src/gdevpdfd.c]
2000-03-10T03:47:37.000000Z lpd
Fix: In-line images emitted an extra 'q' (gsave), causing the CTM to become
incorrect, entries to pile up on the dictionary stack, and an invalidrestore
error to occur at the end of the page.
[src/gdevpdfi.c]
2000-03-10T03:45:29.000000Z lpd
Clears the glyf and loca offsets in TrueType fonts that lack these tables,
so that clients who care can tell whether the font is being downloaded
incrementally.
[src/gstype42.c]
2000-03-10T03:44:33.000000Z lpd
Fix: The terminating $ on the $Id: line in gsmalloc.c was missing, and
dwuninst.rc lacked a $Id: line.
[src/dwuninst.rc src/gsmalloc.c]
2000-03-10T03:43:06.000000Z lpd
Fix: (%os%) currentdevparams didn't return (fixed) values for
InitializeAction, Mounted, Removable, Searchable, SearchOrder, and
Writeable, or (meaningful) values for BlockSize, Free, and LogicalSize.
Currently, the latter values are dummies.
[src/gsiodev.c]
2000-03-10T03:40:13.000000Z lpd
Changes the sbuf_min_left macro to a procedure for readability and in
preparation for later revision.
[src/stream.h src/stream.c]
2000-03-10T03:38:50.000000Z lpd
Fix: When reading the strings of a binary object sequence, having to get
more data from a procedure-based stream sometimes caused a syntaxerror.
Fix: If the reserved (0) field in binary objects or binary object sequences
was not 0, no syntaxerror occurred.
[src/iscanbin.c]
2000-03-10T03:37:14.000000Z lpd
Fix: If an error occurred while loading a font, it wouldn't produce an error
message. (This is a 'fix' of a 'fix' of a 'fix': it might well break
something else.)
[lib/gs_type1.ps]
2000-03-10T03:35:37.000000Z lpd
Updates the pf2afm.ps utility with a revised version from its authors.
[lib/pf2afm.ps]
2000-03-10T03:34:44.000000Z lpd
Fix: The loader for the stochastic halftone incorrectly assumed that the
resource file left the resource on the stack, causing a stackunderflow
error.
[lib/stocht.ps]
2000-03-10T03:33:21.000000Z lpd
Increases the stack size for the PC platforms, since a user had reported
that the OS/2 stack size was too small.
[src/dw32c.def src/dwmain32.def src/gsos2.def]
2000-03-10T03:31:39.000000Z lpd
Fix: There were extraneous 'def' commands that caused definitions to be made
in the wrong dictionary.
[lib/gs_ttf.ps]
2000-03-10T03:22:04.000000Z lpd
Because of rampant confusion, disagreement, and lack of standardization,
removes the RPM-related spec and patch files.
[src/rpm-conf.dif src/gs-fonts.rps src/gs.rps]
2000-03-10T03:16:17.000000Z lpd
In ansi2knr, adds user-contributed support for concatenated string literals
and character constants, and fixes for a couple of minor bugs.
